Created attachment 6585 [details]
This makes the Special:Listusers page work correctly.

Opening the page gives the following backtrace:

A database error has occurred
 Query: SELECT user_name,MAX(user_id) AS user_id,MAX(user_editcount) AS edits,COUNT(ug_group) AS numgroups,MAX(ug_group) AS singlegroup,MIN(user_registration) AS creation,ipb_deleted FROM mwuser LEFT JOIN user_groups ON user_id=ug_user

Software versions installed:
MediaWiki  1.16alpha-wmf
PHP  5.2.9 (apache2handler)
PostgreSQL  8.2.13

Below I'll attach a simple patch which fixes the query (the fix isn't very elegant, but works).
