I can't reproduce this --- I get
Constraints: ((ptype >= 0) AND (ptype <= 8))
((((structure = 'L'::bpchar) OR (structure = 'C'::bpchar)) OR (structure
= 'U'::bpchar)) OR (structure = 'O'::bpchar))
(((department ISNULL) AND (parent_id ISNULL)) OR ((department > ''::text)
AND (parent_id > ''::bpchar)))
(((ptype >= 2) AND (ptype <= 4)) OR (ptype = 8))
However, I had to guess about the referenced tables, and possibly I
guessed wrong. Could you supply their declarations too?
