Hi,
I went over this patch set, don't really have all that much to say
except it looks good for the most part (details inline).

Hmm IIUC this removes ability of REPLICATION role to subscribe to
publications. I am not quite sure I like that.

cache the acl result so performance impact should be negligible.
