pg_dump: could not find namespace with OID

In fact I have fixed my database (source code rocks!) but I thought I would
share my experience with the list in case anyone else sees this. I am
running PostgreSQL 7.3.2 on i386--netbsdelf. I created two user defined
types, glaccount and section. See attached SQL file that creates the type.
Somehow I created two rows for each type in the pg_opclass table, one correct
and one with NULL entries in opcnamespace and opcowner. That's what was
causing the problem I was seeing. I simply removed the bogus rows and
pg_dump worked again.

As far as I can tell there was nothing else affected but if anyone wants me to
test something I still have a copy of the broken database around to try
things on.

Should those fields be NOT NULL to protect against this?
