One thing I was thinking about at my job which I would really have
liked is some kind of version control linked with the database. Say for
example I'd be able to 'checkout' a database function, edit it and
check it in again. This would require some kind of backing store and I
was wondering whether that would be in the database too.

I always found it annoying when I had function definitions in seperate
files which could be checked into CVS, but there was no guarentee that
those files had any relationship with what was in the database.

Maybe I should sketch something out that could be merged with psql or
something... I don't suppose anything like this exists anywhere
already?
