DROP INDEX iwl_prefix;
CREATE UNIQUE INDEX iwl_prefix_title_from ON iwlinks (iwl_prefix, iwl_from, iwl_title);
Attempt at changing postgres as per r66892 OverlordQ or someone, can you review please? 2010-05-25 21:36:56 +00:00			`DROP INDEX iwl_prefix;`
Rename the iwl_prefix_from_title index (again) to iwl_prefix_title_from and change the field order accordingly. Fixed r66892 which inserted iwl_from into the index (which was a good thing) but put it in the wrong place. I went out of my way to make sure the index isn't dropped and recreated needlessly, but since I don't know how to do the drop-index-if-exists thing in the Postgres updater, I left that out. The Postgres updater will now create the new index without dropping any old incarnations if present. I did create the patch files with the DROP INDEX statements to make it easier to add this behavior. Also tweak ApiQueryIWBacklinks to use this index properly. 2010-07-22 08:52:58 +00:00			`CREATE UNIQUE INDEX iwl_prefix_title_from ON iwlinks (iwl_prefix, iwl_from, iwl_title);`
