About preceding note, you shouldn't use pg_num_rows() for this.
You should have instead a look at pg_affected_rows().

Not sure why this documentation doesn't have the following note:
Note: Use pg_affected_rows() to get number of rows affected by INSERT, UPDATE and DELETE query.

Found on other resources. Adding here in case someone else is looking for the info.
