I can now see the list of cities in the dropdown filter box but when I choose a city it has no effect. There is an error message:

^<br /><br />SELECT * FROM m_user WHERE city = "Barcelona" AND id IN(16,7651,4400,4924,8241,2153,5709,...,456 in C:\Apache2\htdocs\moodle\lib\weblib.php on line 6991
I think Barcelona should be in single quotes (for Postgres anyway).
