# 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:

```sql
 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.
