multiple counts using CASE

Howdy

Running Postgres 7.1.3 on RedHat Linux 7.2 kernel
2.4.7 - 10.

Wonder if it is possible to get multiple counts
from ONE query using the CASE statement.

I'm trying to set something up like this:

select count (*)
case
        when logic = '1' then 'First'
        when logic = '2' then 'Second'
        when logic = '3' then 'Third'
        else 'Error'
end as 'Count'
from temp_table
;

I wonder if this is even possible?  Maybe I can
try to create a variable (place holder) and
loop?  I don't want to have to create many
versions of one program to count for each "logic"
in the table.

Suggestions?

Thanks!
