Comparison with pg_stat_statements

The pg_stat_monitor extension is developed on the basis of pg_stat_statements as its more advanced replacement.

Because of this, pg_stat_monitor inherits the columns available in pg_stat_statements and provides additional ones.

Note

pg_stat_monitor and pg_stat_statements process statistics data differently. Because of these differences, memory blocks and WAL (Write Ahead Logs) related statistics data are displayed inconsistently when both extensions are used together.

To see all available columns, run the following command from the psql terminal:

\d pg_stat_monitor;

The following table compares the pg_stat_monitor (PGSM) view with that of pg_stat_statements (PGSS).

Note

The column names differ depending on the PostgreSQL version you are running.

Note

PostgreSQL 19 has not been released yet. pg_stat_monitor supports PostgreSQL 19 beta 3 so that you can test against it. See the 2.4.0 release notes.
