pgsql: Correct sepgsql docs with regard to RLS

Correct sepgsql docs with regard to RLS

The sepgsql docs included a comment that PG doesn't support RLS.  That
is only true for versions prior to 9.5.

Update the docs for 9.5 and master to say that PG supports RLS but that
sepgsql does not yet.

Pointed out by Heikki.

Back-patch to 9.5
