# 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.
|
||
|
||
|
||
| Column name for PostgreSQL 13 and above | Column name for PostgreSQL 11 and 12 | pg_stat_monitor | pg_stat_statements
