Ok. That's what I suspected. Thanks!

Hmm, okay. So in versions greater than 7.1, I can not simply use a normal
PreparedStatement and setBinaryStream(), as suggested in the documentation?
Is this for some technical reason or is this method now deprecated?
I am only getting timeouts on postgresql.org at the moment, so perhaps this is
explicitly stated in the docs, but can I safely assume that any usage of the
Large Object Manager as part of a transactions whose queries are otherwise
done through normal JDBC channels, will not cause any interference between
the JDBC API and the LO manager? I.e., is it "safe" to intermix usage of
large objects with normal statements through JDBC?
