you missed my point. some distro's (red hat, suse, mandrake, etc..)
backpatch into their distributed packages separate of the packages
original source tree. this is great for folks who may want/need a new
change, but can't upgrade to latest source for some reason.

I wasn't thinking of PostgreSQL as a distro, but actually I think that
view is somewhat valid, since there are enough add ons to core that one
could modify without having to make huge changes. 

As Tom pointed out, with the restriction of not being able to initdb,
you're probably pretty limited on what you can push back, but I think
there's still enough there that folks might want to look at it. (The
recent bugs in pltcl handling dropped columns come to mind, though maybe
Tom backpatched those? Cant recall)
