Converts a write-ahead log location to the name of the WAL file holding that location. Note that pg_is_wal_replay_paused() returns whether a request is made. If applied directly to a table column value, this reflects any compression that was done. For example, to get the total size of all indexes attached to the film table, you use the following statement: To get the size of a tablespace, you use the pg_tablespace_size() function. 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. For a relation in the database's default tablespace, the tablespace can be specified as zero. Returns true if recovery is still in progress. These functions may be executed only during recovery. If streaming replication is disabled, the paused state may continue indefinitely without a problem. Finishes performing an on-line backup. If streaming replication is in progress then WAL records will continue to be received, which will eventually fill available disk space, depending upon the duration of the pause, the rate of WAL generation and available disk space. pg_replication_origin_advance ( node_name text, lsn pg_lsn ) void.

Just for info, I have got the excelent answer from @aib and modified it a little for: On materialized view we can use index for refreshing materialized views concurrently, which allows using them while updating. PHYSICAL. Returns the number of pages removed from the pending list. Works with PostgreSQL. We can get the size of a table using these functions. Cancels the current query of the session whose backend process has the specified process ID. (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.) 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. The functions above that operate on tables or indexes accept a regclass argument, which is simply the OID of the table or index in the pg_class system catalog. to report a documentation issue. The size column is the size of the table in MB. pg_copy_logical_replication_slot ( src_slot_name name, dst_slot_name name [, temporary boolean [, plugin name ]] ) record ( slot_name name, lsn pg_lsn ).
