Stephen Frost dcb467b8e2 Fix pg_dump handling of extension config tables ... Since 9.1, we've provided extensions with a way to denote "configuration" tables- tables created by an extension which the user may modify. By marking these as "configuration" tables, the extension is asking for the data in these tables to be pg_dump'd (tables which are not marked in this way are assumed to be entirely handled during CREATE EXTENSION and are not included at all in a pg_dump). Unfortunately, pg_dump neglected to consider foreign key relationships between extension configuration tables and therefore could end up trying to reload the data in an order which would cause FK violations. This patch teaches pg_dump about these dependencies, so that the data dumped out is done so in the best order possible. Note that there's no way to handle circular dependencies, but those have yet to be seen in the wild. The release notes for this should include a caution to users that existing pg_dump-based backups may be invalid due to this issue. The data is all there, but restoring from it will require extracting the data for the configuration tables and then loading them in the correct order by hand. Discussed initially back in bug #6738, more recently brought up by Gilles Darold, who provided an initial patch which was further reworked by Michael Paquier. Further modifications and documentation updates by me. Back-patch to 9.1 where we added the concept of extension configuration tables.		11 years ago
