Yes, Andrew Sullivan even opened a PgFoundry project and a mailing list. 
But up to now, only the GORDA project has proposed some hooks.

For Postgres-R, I definitely don't want to settle for any hooks, yet, 
because I want to keep flexible. Hooks would only get into my way and 
serve no purpose.

Why is that? I can very well change all of the configuration stuff, I 
just don't see no use for that.

...or wait for *the one* superior set of hooks we never can come up with?

Remember that the problem in replication is not interfacing with the 
database. That can and has been solved in multiple different ways. And 
interfaces can change (especially as long as they are still part of 
experimental software).
