Unfortunately not.  See a recent thread in pgsql-sql that discussed

PostgreSQL doesn't have any inherent cross-database capabilities.
You can use dblink to query another database and join the results

what you'd consider "full-featured."  Still, you might want to
check it out if you're not familiar with it.
