New to PostgreSQL Question (Query Optimizer)

Hello,
	I'm newly into PostgreSQL from a SYBASE world and I haven't had a lot of
time to get into the code, so bare with me please.
	Is there a query optimizer in PostgreSQL?  or if not are there plans for
one?  And are there plans for anything like clustered indexes?
	I'm curious because one of the jobs I almost took a few years ago was
working on the query optimizer itself.  And please forgive me current
ignorance of the architecture of your engine.

Thanks, Rick.
