A number of maintenance scripts such as cleanupTitles and cleanupImages currently fail on Wikimedia sites, due to incorrect database connection setup:
$ php maintenance/cleanupTitles.php aawiki
DB connection error: Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2) (localhost)
This ain't good, as it's blocking running of these cleanups...
