Downloading, building, and installing extensions is actually fairly 
standardized already (well, perhaps there are 2 or 3 standards, but CPAN has 
that as well).  I think the inhibitions relate more to the management of what 
is installed.

I imagine we need a package manager inside of PostgreSQL to manage 
installation, setup, removal, dependencies and so on.  Much like rpm or dpkg 
really.  That should replace the current "run this .sql file" mechanism, much 
like rpm and dpkg replaced the "run make install and trust me" mechanism.  I 
have some of this mapped out in my head if there is interest.

We'd also need easy integration with the real rpm and dpkg, so that 
distribution packages can be built easily and I can run

apt-get install postgresql extension1 extension2

and it's all set up.
