The pg_size_pretty() function takes the result of another function and format it using bytes, kB, MB, GB or TB as appropriate. If is_local is true, the new value will only apply during the current transaction. Not the answer you're looking for? As of v14 there appears to be no way to get the combined main, fsm, vm, and init forks (relation_size in the diagram) as one method call. please use If recovery has completed then this will remain static at the time of the last transaction applied during recovery. To fetch the total size of a table including indexes/additional objects, the pg_total_relation_size() function is used in PostgreSQL: The output verified the working of pg_total_relation_size() function as it calculates the table size accurately. 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. Try the Database Object Size Functions. This function is restricted to superusers and members of the pg_monitor role by default, but other users can be granted EXECUTE to run the function. For example, you can get the size of the actor table in the dvdrentalsample database as follows: The pg_relation_size() function returns the size of a specific table in bytes: To make the result more human readable, you use the pg_size_pretty()function.

The following statement returns the size of the pg_default tablespace: The statement returns the following output: To find how much space that needs to store a specific value, you use the pg_column_size() function, for examples: In this tutorial, you have learned various handy functions to get the size of a database, a table, indexes, a tablespace, and a value. Therefore, granting access to these functions should be carefully considered. 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. This is essentially the inverse mapping of pg_relation_filepath. The function returns the number of new collation objects it created. To get the total size of a table, you use the pg_total_relation_size () function. 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. Basic usage example for pg_relation_size(): Attempting to query the size of a non-existent relation: Providing an OID which does not map to an existing relation: A function for determining the size of a relation's fork. 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. Note that pg_is_wal_replay_paused() returns whether a request is made. The given name can then be used with recovery_target_name to specify the point up to which recovery will proceed.

This is how the pg_size_pretty() function assists us in formatting the database size. If false, the function will return immediately after the backup is completed, without waiting for WAL to be archived. Otherwise, WAL required to make the backup consistent might be missing and make the backup useless. While streaming replication is in progress this will increase monotonically. pg_table_size () is a system function for determining the on-disk size of a relation (a table, an index or a materialized view). pg_table_size: Disk space used by the specified table, excluding indexes (but including TOAST, free space map, and visibility map), pg_relation_size: The size of the main data fork of the relation, so pg_table_size is not only the sum of all the return values of pg_relation_size but you have to add toast size. The bytes read from the file are interpreted as a string in the database's encoding; an error is thrown if they are not valid in that encoding. To solve this problem, PostgreSQL allows a transaction to export the snapshot it is using. Returns the number of new page range summaries that were inserted into the index. to report a documentation issue. Emits a logical decoding message. The desired contents of the backup label file and the tablespace map file are returned as part of the result of the function and must be written to files in the backup area. The copied physical slot starts to reserve WAL from the same LSN as the source slot. See Section8.19 for details. Which version of PostgreSQL am I running?

See Section27.2.5, Section27.2.6, and Chapter50 for information about the underlying features. Note that for most purposes it will be more convenient to use one of pg_total_relation_size() or pg_table_size(). Thanks for contributing an answer to Stack Overflow! 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. Returns a relation's OID given the tablespace OID and filenode it is stored under. Lists the tables or indexes in the partition tree of the given partitioned table or partitioned index, with one row for each partition. as in example? 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. pg_relation_size() was added in PostgreSQL 8.1. fork can be one of the following values (if not specified, defaults to main): The caller does not require any permissions on the relation to determine its size. And pg_total_relation_size is the sum of pg_table_size and pg_indexes_size. A snapshot determines which data is visible to the transaction that is using the snapshot. If you want to list the databases by their size, you should read the following article. Returns the replay location for the replication origin selected in the current session. And pg_total_relation_size is the sum of pg_table_size and pg_indexes_size. pg_last_xact_replay_timestamp () timestamp with time zone. This is primarily useful for setting up the initial location, or setting a new location after configuration changes and similar. Converts this into readable format (kb, mb, gb).

Table9.97 lists functions that provide information about the structure of partitioned tables. On timeout, a warning is emitted and false is returned. Snapshots are exported with the pg_export_snapshot function, shown in Table9.92, and imported with the SET TRANSACTION command. A transaction can export more than one snapshot, if needed. Temporary slots are also released upon any error. Creates a new physical replication slot named slot_name. pg_advisory_lock ( key1 integer, key2 integer ) void. This function is identical to pg_read_file except that it can read arbitrary binary data, returning the result as bytea not text; accordingly, no encoding checks are performed.
