Обсуждение: pgsql: Cleanup slots during drop database

Cleanup slots during drop database

Automatically drop all logical replication slots associated with a
database when the database is dropped. Previously we threw an ERROR
if a slot existed. Now we throw ERROR only if a slot is active in
the database being dropped.
