As postgresql supports many languages like 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.

Hi,

I see from other posts that you are using Python (A lovely language, but
one that does not scale well for my own purposes -- unfortunately) so
this is most likely not relevant to your current situation.

However, for those people who would consider Java, then consider using
JBoss 7, it is very fast and will support very sophisticated web front
ends while allowing very powerful logic written in Java, and can easily
be configured to use PostgreSQL.

The combination of JBoss http://www.jboss.org/overview.html and JEE
(Java Enterprise Edition), is well suited to large projects that can
benefit from multi-core processors and massive amounts of RAM. My own
humble development machine has a mere 4 cores and 8GB, but production
machines can easily use a terrabyte of memory and many more cores.
Eclipse is an IDE that is well suited for developing applications in
Java, and can be configured to develop applications for JBoss.

Cheers,
Gavin

I have written a script to install JBoss 7 (a lot easier than for JBoss
4 and earlier!) and convert it to use PostgreSQL 9.1 beta3. This I am
using to revise my JEE knowledge and get to grips with version 6 of JEE.
