Support for Synonyms?

Hi guys,
I just wonder if there is a similar concept as Oracle's SYNONYM
in PostgreSQL.
Using a synonym, you can basically refer from one Schema to another.
For Example in Schema A you have a table called Test.
In Schema B you can then create a synonym to this table:
CREATE SYNONYM Test for A.Test.
This way, you no longer need to reference Test with A.
when selecting from it coming from schema B.

I checked in the manual, but didn't find such a concept.

Thnaks for your help,

Cheers, Dani
