Well, before that, you need to know what hooks you need. And that again 
involves lots of implementation details. Thus better first implement 
without hooks, otherwise you might later notice that there is something 
you didn't think of.

That was just an example. Postgres-R actually already does a lot behind 
the scenes if you type that command. So, yes, the horse definitely came 
before the cart.

Okay. After reading the tsearch2 discussion I got another feeling, but 
that might just have been me.
