ALTER TABLE /*$wgDBprefix*/archive
  ADD ar_page_id int unsigned;
Fixups for page id field in the archive table: * Make the field nullable for consistency with ar_rev_id and ar_text_id and between MySQL and PostgreSQL and generally so you can cleanly tell between bogus fields and ones that predate use of the field * Remove duplicate incorrect adding of the field for postgres * Rename to ar_page_id for consistency with ar_rev_id and ar_text_id * Rename the patch file for naming consistency Note that there's no documentation of this schema change in the release notes either, which bugs me a bit. 2007-08-11 14:43:47 +00:00			`-- Reference to page_id.
