Here's a combination of all the patches I'm currently waiting

Browse Source 
for against a just updated CVS tree. It contains

        Partial new rewrite system that handles subselects,  view
        aggregate  columns, insert into select from view, updates
        with set col = view-value and select rules restriction to
        view definition.

        Updates  for  rule/view  backparsing utility functions to
        handle subselects correct.


        New system views pg_tables and pg_indexes (where you  can
        see the complete index definition in the latter one).

        Enabling array references on query parameters.

        Bugfix for functional index.

        Little changes to system views pg_rules and pg_views.


    The rule system isn't a release-stopper any longer.

    But  another  stopper  is  that  I  don't  know if the latest
    changes to PL/pgSQL (not already in CVS) made it  compile  on
    AIX. Still wait for some response from Dave.
