help..postgresql mulyiple return values

hi,
im new in postgresql, generally new in databases.

im trying to make a function using PGAdminIII which returns several types,
example, my query is:

"select count(id) as requests, organization from connection_requests group by organization"

id is of type int8, organization is of type varchar(50).

basically the query would return coun(id), and a varchar(50) which is organization.

i really dont know what to put on the return type.

what would be the best solution?

hope to hear from you guys asap..

thank you
