Can you be specific? Something I can add to the TODO list.

Database based access for users so that each user can be giving access
to a particular database only. More permissions for each databse user:
Create, Drop, Select, Insert etc. Possibly table based
authentification as well.

I needed to do that for the web database that I'm setting up. We have
20000 users and each (potentially) needs a separate database which is
only accessible to them. Rather than having 20000 lines in pg_hba.conf,
I've patched Postgres so that the special token "%username" in the
database field of pg_hba.conf allows access only to the username which
is connecting. (I chose the leading "%" so that it couldn't clash with
a real database name.) Since the patch is against 6.1 rather than
6.2beta, I hadn't made it public. Here it is in case it's of interest.

I have re-generated this patch for the current source, and changed
'%username' to 'sameuser'. I added documentation in pg_hba.conf.

Patch applied. This is a nice feature.
