Although postgres itself doesn't seem to have a thing such as Informix' "synonym" which allows more-or-less transparent
accessto a table in a remote database, there is a utility in contrib directory of the postgres source called dblink,
whichallows access to different instance of postgres by opening connections. I have only played with it for testing and
haveno idea of its limitations, but it might serve your needs.

Subject: [SQL] Queries across multiple database
I am in the process of migrating the databases for an application from mysql
to postgres. The application is uses several different databases. From
what I have read, postgres still does not support queries across multiple
databases. If this is still true, does anyone have any tricks to get around
this? I'm sure this is a common problem for people migrating from mysql.
The obvious answer is to just migrate everything into one larger postgres
database, but I would like to avoid this if possible - many a line of could
would need to be touched if this was done.
Thanks,
Garth
