Do you have right permissions for DB and dirs with LO dumps?

Hmm.. may be, sounds curious if everythig is right on mew DB.

The LO dump format is same for 7.0 and 7.1. If you use pg_dumplo from
7.1 for LO data from 7.0 you probably import all without problems.

Means "brute filecopy" copy backend store files? IMHO it's really brutal
way, more standard is dump out and import all back to new DB.

The pg_dump in 7.1 dumping LO too. My pg_dumplo is a crutch for old PG
versions and for export/import without spec. oid operations (like new
pg_dump)
