I didn't quite parse that. Using recursive queries, it should be able to pretty easily query out, given a table name, all tables that link to that table and the columns of the keys in the constraints (and, if necessary, the links from other tables to those tables). If I was looking for specific *records*, not tables and columns, I would probably be generating a query from the above. (If I'm understanding you properly that is). merlin -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
