I've got a 7.4 database that gives postgres an "out of memory" error
when restoring into a 32-bit build 8.1, yet restores into a 64-bit
build of 8.1.
I dumped a 7.4.9 database, running on Debian/testing, 32-bit, using
this command:
pg_dump --format=c --blobs production --verbose >production.dbarchive
This results in a 37G file. The great bulk of this database is in
large objects.
I can restore it into 8.1.0, running on Debian testing, 64-bit, using
this command:
pg_restore -d production production.dbarchive
However, I cannot restore it into 8.1.3, running on Debian testing,
32-bit, using the same command. I get this in the postgres log:

What other information can I supply? What experiments should I do?
Thanks in advance for any help you can offer.
