selecting data from multiple DBs

Hello .. on the same machine i have several DBs.. i owuld like to do a query
that joins results from different ones .. is ther eany way to do it in
postgres? i would expect something list

select foo1 from database1.mytable,database2.mytable etc.. ec.

but i have found no way..

i woudl be very surprised if there was no way to do it.. since Postgres has the
UID concept on any record of any database..
thanks for any info
