[GENERAL] pg_dump dumping data in order? (used to in 7.4 but not now in 8?)
When I do a pg_dump, (--data-only), PG7 used to dump the data out in order, so that all foreign-key checks worked correctly when loading the data back in. Now it seems with PG8 it's dumping it completely out of order (one of my completely foreign-key join tables first!) - and I can't get it to dump in the correct order. Anyone know a solution to this, to get a data dump to export in a correct order so that foreign-key checks will work when loading that data in again? ---(end of broadcast)--- TIP 3: if posting/reading through Usenet, please send an appropriate subscribe-nomail command to [EMAIL PROTECTED] so that your message can get through to the mailing list cleanly

If it did so, it was by pure luck. In general it is not possible for pg_dump to guarantee this works; consider circular FK constraints, or FK constraints added since the dump occurred. In view of that, pg_dump has never tried to ensure that data-only dumps are in a valid order at all. The usual approach is to use --disable-triggers to short-circuit the FK constraints during the load. regards, tom lane ---(end of broadcast)--- TIP 2: you can get off all lists at once with the unregister command (send unregister YourEmailAddressHere to [EMAIL PROTECTED])
