Ok, works for me. I'll prepare a larger patch to do that.
Since we're on a removal-spree, it'd also be nice to get rid of the
"fast-path" function call interface, PQfn(). However, libpq is using it
internally in the lo_*() functions, so if we remove it from the server,
lo_*() will stop working with old libpq versions. It would be good to
change those functions now to use PQexecParams() instead, so that we
could remove the fast-path server support in the future.
