And if there's an API change everything will blow up.
I would suggest we start with what is (I think) simplest and clearest:
. catalog support via a simple extension->schema(s) map
. initdb installs standard extensions if it finds them, unless told not to
. support for adjusting search path.
If that gets done nicely for 8.3 we'll be doing well.
