This could be part of an installer for PostgreSQL extensions. See
following email for a proposal on how to deal with extension packaging:

The proposal purposefully let fetching and building steps out of the
database manager itself, and makes it so that building is to be cared
about by distributors. So it would be something like:
create sampledb
pg_pkg fetch pgsampledb

and either
pg_pkg install pgsampledb sampledb
psql sampledb
psql sampledb
sampledb=# install package pgsampledb;

The dependancy system is yet to be though about, but definitely in the
scope of the extension manager.

While at it, calling all those things extensions rather than package
would probably help not confusing people with Oracle compatibility
etc. Last time I checked I didn't find mention of "package" into the
standard, but still.

So PosgtreSQL could have an extension manager at SQL level (create or
replace extension, install extension, or maybe load extension (which
would LOAD the modules associated), etc) with a system command line
tool to fetch & build, etc (pg_ext ?) that source level users and
packagers (distributors) would use?

What do you dear readers think about the "extension" vocabulary?
