Ah, I'd forgotten about that one. geo_distance is part of the
contrib/earthdistance module, as your pg_admin output hints at:

If you want to use that function then install contrib/earthdistance
(you'll have to install contrib/cube first because earthdistance
depends on it). If you're not sure how to install those modules
then look around for files named cube.sql and earthdistance.sql and
load them into your database (cube.sql first).
