Yes, but *HOW* - is it a different file, length is different, what?

I find it unlikely that "2" and "60" were returned by lo_import() as
OIDs available for large-objects. You've either got:
1. Some other part of your application(s) overwriting "value"
2. Old data still in "value"
3. On-disk corruption due to crashes/hardware malfunction.
4. You're not showing real values

Hmm - well it's clearly not right, but I don't see how it can cause
errors like this.
