Use weaker locks when updating pg_subscription_rel
The previously used ShareRowExclusiveLock, while technically probably
more correct, led to deadlocks during seemingly unrelated operations and
thus a poor experience. Use RowExclusiveLock, like for most similar
catalog operations. In some care cases, the user might see an error
from DDL commands.
