Fix tests for Postgres 9.3

Postgres 9.3 turns messages about implicit indexes and sequences from NOTICE
to DEBUG1 so the tests fail with a default 9.3 server configuration because
the client doesn't get any NOTICE. Fix it by also asking for DEBUG1 messages
from the server when testing against Postgres >= 9.3.
