And don't use bytea until 7.4, when the new V3 protocol is on unless you
have real security issues with other people being able to read your LOB
(PostgreSQL LO facility is not secure while bytea is).
You would need a patch to use bytea with 7.3 but it is not an ideal
solution so you should avoid it (it has not been incorporated to the
sources so you would have to get into the business of building the
driver yourself).
