-- Rename the archive.ar_usertext_timestamp index to usertext_timestamp.
-- This is for MySQL only and is only necessary on wikis freshly installed on
-- 1.28.0 when bug T154872 was present. The patch will probably be removed in
-- 1.29 since we plan on renaming the index properly to ar_usertext_timestamp.
ALTER TABLE /*$wgDBprefix*/archive
	DROP INDEX ar_usertext_timestamp,
	ADD INDEX usertext_timestamp (ar_user_text,ar_timestamp);
