I've done the parsing of foreign key triggers required in the past for various documentation purposes and it wasn't overly fun -- nor am I sure it's right in all cases. Find 3 triggers with is_constraint true between two tables that match argument sets, split argument list by comma, first 4 aren't so useful, the rest in pairs are source / destination columns. Foreign Key state (deferred, match, etc.) is in the function naming convention. If you want to give it a shot, feel free. Whatever method is in place will need to work on 7.3 for those who didn't use a newer pg_dump on the older database. ---------------------------(end of broadcast)--------------------------- TIP 5: Have you checked our extensive FAQ? http://www.postgresql.org/users-lounge/docs/faq.html
