Reproducible relcache reference leak

When I first log in to psql as a superuser, the first time I try to use
lo_export (), I get a reference leak warning. This does not happen on
subsequent attempts. However I can log out and log back in, and see the
error again the first time I execute the query.

Detail follows. Please CC responses, I'm not on the list.
