On rethinking, since pg_subscription query needs to be run only once
on *any* database to get combined results of all main slots while
pg_subscription_rel query needs to be run on each database having
concerned subscription (and table), does it makes sense to separate
the 2 queries instead of having UNION ? Thoughts?
