OK, part of the problem might be the lo_create function which
creates a large object using the functions inv_create and
inv_close.
inv_create uses TupleDescInitEntry to create tuple descriptors (I think)
but it never seems to free these tuple descriptors.
The function FreeTupleDesc seems to have been created for this purpose.
As I'm new to postgresql this I'm wondering if I'm on the right track.
Anyway I'll give it a try and see if the problem goes a way.
