For example, the following statement returns the size of the dvdrental database: The statement returns the following result: To get the size of each database in the current database server, you use the following statement: To get total size of all indexes attached to a table, you use the pg_indexes_size() function. The functions shown in Table9.100 manage advisory locks. All trademarks property of their respective owners. Obtains a shared session-level advisory lock if available. These must be stored as part of the backup and are required as part of the restore process. Advances the current confirmed position of a replication slot named slot_name. The number of distinct words in a sentence. Example #2: How to Use the pg_size_pretty() Function With the pg_database_size() Function? (Note that these maintenance tasks are normally done automatically by autovacuum; use of these functions is only required in special cases.) pg_advisory_lock_shared ( key bigint ) void, pg_advisory_lock_shared ( key1 integer, key2 integer ) void. Why do we kill some animals but not others? Behaves just like the pg_logical_slot_peek_changes() function, except that changes are returned as bytea. But note that any database changes made by any one of these transactions remain invisible to the other transactions, as is usual for changes made by uncommitted transactions. pg_size_pretty: Other functions return results in bytes. pg_replication_origin_drop ( node_name text ) void. Returns true if recovery pause is requested. The level value is 0 for the input table or index, 1 for its immediate child partitions, 2 for their partitions, and so on. If one needs to see both tables and indexes, This returns sorted by name though, the top answer returns sorted by size descending, By far the simplest answer for a quick view of size. psql -h <server_name> -U <username> -W Step 2. The function returns the number of new collation objects it created. Example #3: How to Get the Total Size of a Table Including Indexes/Additional Objects?The pg_relation_size() function fetches only the tables size, and it omits the size of indexes/additional objects. total_size - total table size data_size - size of table's rows external_size - size of external elements, such as indexes etc. The basic syntax of the pg_relation_size() function will be as follows: Example #1: How to Use the pg_relation_size() function in PostgreSQL? There's a couple of examples showing how to slide and dice the available information various ways at http://wiki.postgresql.org/wiki/Disk_Usage. Removes the BRIN index tuple that summarizes the page range covering the given table block, if there is one. The size column is the size of the table in MB. Returns the current value of the setting setting_name. If two sessions just start their transactions independently, there is always a possibility that some third transaction commits between the executions of the two START TRANSACTION commands, so that one session sees the effects of that transaction and the other does not. How to Find The Size of all Databases in PostgreSQL, Your email address will not be published. While recovery is paused, no further database changes are applied. This is essentially the inverse mapping of pg_relation_filepath. How can I drop all the tables in a PostgreSQL database? (Typically this would be the name under which the backup dump file will be stored.) Lets utilize pg_size_pretty() function to convert the resultant sizes into human-readable format: This is how you can fetch the size of all the databases using a single statement. - from the postgres docs. pg_relation_filepath ( relation regclass ) text. Note that for most purposes it will be more convenient to use one of pg_total_relation_size() or pg_table_size(). pg_try_advisory_lock ( key bigint ) boolean, pg_try_advisory_lock ( key1 integer, key2 integer ) boolean. The process ID of an active backend can be found from the pid column of the pg_stat_activity view, or by listing the postgres processes on the server (using ps on Unix or the Task Manager on Windows). What is the arrow notation in the start of some lines in Vim? This page was last edited on 20 October 2022, at 16:16. If you want to know how much space your tables are using, use pg_table_size and pg_total_relation_size to think about them -- one number is table-only, and one number is table + indexes. Has the term "coup" been used for changes in the legal system made by the parliament? The table was restored from dump just a while ago, and no writes were made since. >=8.1. A transaction can export more than one snapshot, if needed. By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy. Try the Database Object Size Functions. If recovery has completed then this will remain static at the time of the last transaction applied during recovery. See also ALTER COLLATION. Lets run the below statement to see the total size of the targeted table/relation: The output shows that the pg_relation_size() function successfully returned the accurate size of the targeted relation. The summation of the data and indices size is around 26 GB, but the total relation size is near 160 GB. Converts a write-ahead log location to a WAL file name and byte offset within that file. Other than quotes and umlaut, does " mean anything special? pg_reload_conf () boolean Causes all processes of the PostgreSQL server to reload their configuration files. This is like brin_summarize_new_values except that it only processes the page range that covers the given table block number. So in the event of a crash, the slot may return to an earlier position. These functions may be executed both during recovery and in normal running. The snapshot is available for import only until the end of the transaction that exported it. on disk. Releases a previously-acquired exclusive session-level advisory lock. For storage file layout fsm, vm, and init mean, you can get from this link like @jmelesky mentioned. What does a search warrant actually look like? pg_copy_physical_replication_slot ( src_slot_name name, dst_slot_name name [, temporary boolean ] ) record ( slot_name name, lsn pg_lsn ). The slot will not be moved backwards, and it will not be moved beyond the current insert location. To use this function, you must have CONNECT privilege on the specified database (which is granted by default) or have privileges of the pg_read_all_stats role. How to find data length and index length of particular tables in a postgresql schema? Releases a previously-acquired shared session-level advisory lock. These memory contexts will be logged at LOG message level. This can be used to pass generic messages to logical decoding plugins through WAL. The pg_tablespace_size() function accepts a tablespace name and returns the size in bytes. Returns no rows if the relation does not exist or is not a partition or partitioned table. Get table size of partitioned table (Postgres 10+). When the server has been started normally without recovery, the function returns NULL. This is primarily useful for setting up the initial location, or setting a new location after configuration changes and similar. For logical slots, this must be called while connected to the same database the slot was created on. From that, you can tell pg_table_size is the sum of all the return values of pg_relation_size. In Oracle I had a nasty long query that looked at user_lobs and user_segments to give back an answer. For example, you can get the size of the actor table in the dvdrental sample database as follows: select pg_relation_size ( 'actor' ); Code language: SQL (Structured Query Language) (sql) The pg_relation_size () function returns the size of a specific table in bytes: Psql displays the size of the database. Returns the time stamp of the last transaction replayed during recovery. Returns true if the lock is successfully released. Deletes a previously-created replication origin, including any associated replay progress. pg_logical_slot_peek_changes ( slot_name name, upto_lsn pg_lsn, upto_nchanges integer, VARIADIC options text[] ) setof record ( lsn pg_lsn, xid xid, data text ). postgresql database-size size Share Improve this question If offset is negative, it is relative to the end of the file. This forces an immediate checkpoint which will cause a spike in I/O operations, slowing any concurrently executing queries. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. If the lock was not held, false is returned, and in addition, an SQL warning will be reported by the server. pg_database_collation_actual_version ( oid ) text. Only files within the database cluster directory and the log_directory can be accessed, unless the user is a superuser or is granted the role pg_read_server_files. set_config ( setting_name text, new_value text, is_local boolean ) text. Some of these functions take an optional missing_ok parameter, which specifies the behavior when the file or directory does not exist. Why is the article "the" used in "He invented THE slide rule"? This is also allowed if the calling role is a member of the role whose backend is being terminated or the calling role has privileges of pg_signal_backend, however only superusers can terminate superuser backends. Forces the server to switch to a new write-ahead log file, which allows the current file to be archived (assuming you are using continuous archiving). pg_size_pretty() is a system function for displaying a size in bytes into human-readable format. A request doesn't mean that recovery stops right away. This gives table size per parent table even if we have multiple partition levels: WITH RECURSIVE tables AS ( SELECT c.oid AS parent, c.oid AS relid, 1 AS level FROM pg_catalog.pg_class c LEFT JOIN pg_catalog.pg_inherits AS i ON c.oid = i.inhrelid -- p = partitioned table, r = normal table WHERE c.relkind IN ('p', 'r') -- not having a parent . Finishes performing an on-line backup. Cleans up the pending list of the specified GIN index by moving entries in it, in bulk, to the main GIN data structure. If false, an error is raised.

If hot standby is active, all new queries will see the same consistent snapshot of the database, and no further query conflicts will be generated until recovery is resumed. Nothing. If temporary is omitted, the same value as the source slot is used. These are all read-only operations and do not require superuser permissions. Connect and share knowledge within a single location that is structured and easy to search. If you want to know how much space your tables are using, use pg_table_size and pg_total_relation_size to think about them -- one number is table-only, and one number is table + indexes. Are there conventions to indicate a new item in a list? Tables which have both regular and TOAST pieces will be broken out into separate components; an example showing how you might include those into the main total is available in the documentation, and as of PostgreSQL 9.0 it's possible to include it automatically by using pg_table_size here instead of pg_relation_size: Note that all of the queries below this point on this page show you the sizes for only those objects which are in the database you are currently connected to. Returns the name, size, and last modification time (mtime) of each ordinary file in the server's pg_logical/mappings directory.

(Note that for most purposes it is more convenient to use the higher-level functions pg_total_relation_size or pg_table_size, which sum the sizes of all forks.) Note that pg_is_wal_replay_paused() returns whether a request is made. For details about proper usage of these functions, see Section26.3. pg_create_restore_point ( name text ) pg_lsn. You can use the pg_file_settings, pg_hba_file_rules and pg_ident_file_mappings views to check the configuration files for possible errors, before reloading. Use of this function is restricted to superusers. The updated slot position information is written out at the next checkpoint if any advancing is done. There is an optional parameter of type boolean. pg_table_size () was added in PostgreSQL 9.0. pg_log_backend_memory_contexts can be used to log the memory contexts of a backend process. So far, I've come up with the following: SELECT SUM(pg_relation_size(oid, 'main')) AS main_size, SUM(pg_relation_size(oid, 'vm')) AS vm_size, SUM(pg_relation_size(oid, 'fsm')) AS fsm_size, SUM( CASE reltoastrelid WHEN 0 THEN 0 ELSE pg_total_relation_size . If you want to list the databases by their size, you should read the following article. You can use pg_walfile_name_offset to extract the corresponding write-ahead log file name and byte offset from a pg_lsn value. The pg_relation_size () function is used to get the size of a table.

Check the storage file layout for some info about what fsm, vm, and init mean, and how they're stored on disk. This function corresponds to the SQL command SET. For most relations the result is the same as pg_class.relfilenode, but for certain system catalogs relfilenode is zero and this function must be used to get the correct value. SELECT pg_size_pretty(pg_database_size('<db_name>')); Step 3. Lets execute the below-given command to see the total size of the selected database: The output shows that the pg_database_size() function successfully returned the size of the selected database.

This can be used with pg_stat_replication or some of the functions shown in Table9.89 to get the replication lag. Scans the specified BRIN index to find page ranges in the base table that are not currently summarized by the index; for any such range it creates a new summary index tuple by scanning those table pages. pg_drop_replication_slot ( slot_name name ) void. I am pretty sure after looking into the below image you will get a good understanding of various size relationships. Use the pg_database_size() function to get the Database size. Obtains a shared transaction-level advisory lock if available. (This is initiated by sending a SIGHUP signal to the postmaster process, which in turn sends SIGHUP to each of its children.) What's the difference between pg_table_size(), pg_relation_size() & pg_total_relation_size()? This function is restricted to superusers by default, but other users can be granted EXECUTE to run the function.

Which one is relevant to the actual disk space my table is using? Otherwise, if recovery is still in progress this will increase monotonically. The functions shown in Table9.88 send control signals to other server processes. Filenames beginning with a dot, directories, and other special files are excluded. The history file includes the label given to pg_backup_start, the starting and ending write-ahead log locations for the backup, and the starting and ending times of the backup. As long as the exporting transaction remains open, other transactions can import its snapshot, and thereby be guaranteed that they see exactly the same view of the database that the first transaction sees. I understand the basic differences explained in the documentation, but what does it imply in terms of how much space my table is actually using? pg_total_relation_size: Total size of a table. Behaves just like the pg_logical_slot_get_changes() function, except that changes are not consumed; that is, they will be returned again on future calls. Example #3: How to Fetch the Size of All Databases in Postgres? How to Find The Size of all Databases in PostgreSQL. pg_advisory_lock ( key1 integer, key2 integer ) void. Request to pause recovery. The insertion and flush locations are made available primarily for server debugging purposes.

To get the total size of a table, you use the pg_total_relation_size() function. Filenames beginning with a dot, directories, and other special files are excluded. These files must not be written to the live data directory (doing so will cause PostgreSQL to fail to restart in the event of a crash). The tbl_rows column is the total number of rows in the table, including rows that have been marked for deletion but not yet . Emits a logical decoding message. pg_replication_origin_session_progress ( flush boolean ) pg_lsn. I'm coming to Postgres from Oracle and looking for a way to find the table and index size in terms of bytes/MB/GB/etc, or even better the size for all tables. Multiple session-level lock requests stack, so that if the same resource identifier is locked three times there must then be three unlock requests to release the resource in advance of session end. By default or when this parameter is true, pg_backup_stop will wait for WAL to be archived when archiving is enabled.

Check how much size columns take up in a postgresql Table? The result is the ending write-ahead log location plus 1 within the just-completed write-ahead log file. Creates a replication origin with the given external name, and returns the internal ID assigned to it. Note that the units are powers of 2 rather than powers of 10, so 1kB is 1024 bytes, 1MB is 10242 = 1048576 bytes, and so on. Saves the transaction's current snapshot and returns a text string identifying the snapshot. These functions may be executed only during recovery. If streaming replication is disabled, or if it has not yet started, the function returns NULL. This is what initdb uses; see Section24.2.2 for more details. If streaming replication is disabled, the paused state may continue indefinitely without a problem. Sets the parameter setting_name to new_value, and returns that value. Computes the total disk space used in the tablespace with the specified name or OID. Returns the name of the slot and the actual position that it was advanced to. If the optional second parameter is given as true, it specifies executing pg_backup_start as quickly as possible. And pg_total_relation_size is the sum of pg_table_size and pg_indexes_size. While streaming replication is in progress this will increase monotonically. The functions shown in Table9.94 calculate the disk space usage of database objects, or assist in presentation or understanding of usage results.
