Re: trouble migrating large objects from 7.1.3 to 7.3.2

Tom/Philip - I've tried with the -o option on the dump side only & I get the
original problem - the OID's in the new database just increase by 2.  The data
is there, though, because the disc space decreases.

I was originally running pg_dump & pg_restore without the -o options, but when
I saw it wasn't working, I tried using the -o options in various combinations
(pg_ dump only, pg_restore only & both).

From what the docs say, I shouldn't need these options, but I tried them as a
last resort.

Philip Warner points out that "-o" for pg_restore means "restore in OID
order", which requires seeking in the input file, which won't work on
piped input.  Try it without the -o on the restore side.  (Offhand I'd
bet that you don't really want -o on the dump side, either, but that's
a different issue.)

The error messages do leave something to be desired :-(
