pgsql: Fix NULL input behaviour of pg_stat_get_replication_slot(). - Mailing list pgsql-committers

Fix NULL input behaviour of pg_stat_get_replication_slot().

pg_stat_get_replication_slot() accidentally was marked as non-strict, crashing
when called with NULL input. As it's already released, introduce an explicit
NULL check in 14, fix the catalog in HEAD.

Bumps catversion in HEAD.
