Yes, and the CPAN analogy that has been in several minds, but it only 
goes so far. Perl and Ruby are languages - Postgres is a very different 
animal.

We do in fact have some support for building / installing some modules 
in a standard way. It's called pgxs and it is used by quite a number of 
existing modules.

One thing that might be worth looking at is an install command at the 
SQL level, so the "INSTALL foo" would run the install script for the foo 
module in the current database, assuming it's in the standard location.

We don't have a central repository of non-standard modules, like CPAN, 
and so of course no facility for fetching / building / installing them.

Not all modules fit a single pattern, either. There are addon languages, 
types, and function libraries, as we all as utilities that are not 
installed in the database at all.

Finally, setting up modules so they can be built for Windows, especially 
using MSVC, will probably be quite a challenge.

So if someone wants to make a start on any of this I'm sure we would all 
listen up.

cheers
