Yes, I thought we had that too, but I don't see it.
Actually, you can just use COPY WITH OIDS and insert a large oid. That
will set the counter. That's how pg_dump does it:CREATE TEMPORARY TABLE pgdump_oid (dummy integer);COPY pgdump_oid
WITHOIDS FROM stdin;143655 0\.
This method will only _increase_ the oid.
