It means the descriptor you opened with lo_open isn't open anymore (or
that you're passing the wrong descriptor number, but the former is more
likely). Descriptors are closed at transaction end, so you have to hold
open a transaction block for your entire lo_open .. lo_close sequence.

If it seems "random" then you are probably being careless with
connection pooling. You've got to hold onto the same connection and
same transaction for as long as you're using the LO.
