That's fine, but pg_dump has to continue to work against old servers,
so it's going to have to be coded to ignore inapplicable permissions
anyway. Contorting the server-side code to avoid that is pointless.

You'd have to allow the union of relation and sequence rights during the
conversion to bitmask form in ExecuteGrantStmt, and then check more
closely inside the per-object loop in ExecGrant_Relation, but that
doesn't seem like a showstopper to me. It certainly seems more pleasant
than exposing bizarre restrictions to users because we're sharing code
between the cases.
