Is your feature request related to a problem? Please describe.

PostgreSQL locks often called “write locks” or “exclusive locks,” restrict users from modifying a row or a PostgreSQL table's contents. Rows that have undergone a DELETE or UPDATE operation will be locked solely until the transaction is finished. Hence, this metric will be useful for users to assess the number of locks.

Describe the solution you'd like.

We can query pg_locks, pg_class to count the number of process PIDs
