Maybe it's to late for me to think correctly (actually I'm sure of that). I'm
going to ask anyways.
I have a table like

id int4
user_id int4
photo varchar
image_type char(1)

where image_type is either G or X
What I want to do is have ONE query that gives me the count of images of each
type per user_id.
So if user 3 has 5 photos of type G and 3 photos of type X
I basically want to have a result 5,3
It got to be possible to get a query like that, but somehow it eludes me
tonight.

Any pointers are greatly appreciated.
