Vivekananda,

I hope you just want the first one.  I think what you need is to
re-think your database design.

From the PostgreSQL manual:
"A PostgreSQL database cluster contains one or more named databases.
Users and groups of users are shared across the entire cluster, but no
other data is shared across databases. Any given client connection to
the server can access only the data in a single database, the one
specified in the connection request."
http://www.postgresql.org/docs/8.1/static/ddl-schemas.html

Now your CLIENT can connect to two different databases with two
different connections and ditto for connecting to two different
clusters.

Possible dblink, in the ./contrib directory would help ? I have never had to use it but it seems like it might be what
youneed.

This can be done with DBlink which is a contrib module.
