pl/perl, pl/python etc, supports dblink like functions to connect to
other postgresql servers and now features are in development to use
external data. Postgresql works well on many operating systems and has a
stable and good quality code. As many users are using plpython or plperl
to work on many types of data and to implement logic that can be useful
in web application management.

No, PG has never, and will never, act as an application-server. Are you
really sure you need a full-blown application-server?

If you're familiar with Scala (a language which runs on the JVM) I
really recommend Lift (www.liftweb.net) with PostgreSQL. Definitely the
best. Although Lift has a history of having a steep learning-curve I
always favour maintainability, type-safety and robustness over RAD and
time-to-market. Having said that I honestly think a skilled Lift team is
at least 2x more productive than with any other web-based framework for
building modern UI.

I'm about to post a Lift+JPA+Spring+PostgreSQL example soon which
demonstrates how to use Lift with Spring+JPA+XA(2 phase commit, aka.
distributed transactions). Follow the mailing-list and you'll see it
there soon (I hope): http://groups.google.com/group/liftweb
