Comparing pg_stat_monitor and pg_stat_statements

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

Thus, pg_stat_monitor inherits the columns available in pg_stat_statements plus provides additional ones.

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

 postgres=# \d pg_stat_monitor;

The following table compares the pg_stat_monitor view with that of pg_stat_statements.

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