Right. I didn't mean to imply otherwise. That first line should have read "I
didn't see it documented anywhere that a 0 in attypid of pg_attribute is OK
with dropped columns". My only point was that in the notes it says that
attypid is the OID in pg_type, and that information in that table must match
information in this table else PostgreSQL will fail. However that's not
neccessarily true for dropped columns where there is no match cause attypid
will be 0. Are there other cases where it can be set to 0?
