You cannot do cross database references per se, but you can use schemas, 
which roughly behave like individual databases do in MSSQL. See:
http://www.postgresql.org/docs/7.4/static/ddl-schemas.html

If you really need cross-database queries, see contrib/dblink (which 
would also work across servers), but it isn't as flexible as using schemas.

HTH,
