It should be possible to be in contrib and installed by default, even
with the current tool set, by tweaking initdb to install the contrib
into template1. But that would be a packaging / dependency issue I guess
then.

Of course the extension system would ideally "create extension foo;" for
all foo in contrib at initdb time, then a user would have to "install
extension foo;" and be done with it.
