Ah, right.  IIRC there is a check in COPY to set the OID counter to
max(current OID counter, user-supplied OID).  So you could use this
technique to install all the BLOBs with the right OIDs, as long as
you were careful to load them in OID order: just load another row
into the temp table each time you need to advance the OID counter.
Kinda klugy, but no backend changes needed.

BTW I'd recommend making pgdump_oid a TEMP table, so that it'll go away
by itself.
