Update of /home/projects/pgsql/cvsroot/pgsql/src/backend/optimizer/plan
     from hub.org:/home/projects/pgsql/tmp/cvs-serv27889/src/backend/optimizer/plan

Modified Files:
    createplan.c initsplan.c planmain.c planner.c setrefs.c
    subselect.c

-----------------------------  Log Message  -----------------------------

Subselects in FROM clause, per ISO syntax: FROM (SELECT ...) [AS] alias.
(Don't forget that an alias is required.)  Views reimplemented as expanding
to subselect-in-FROM.  Grouping, aggregates, DISTINCT in views actually
work now (he says optimistically).  No UNION support in subselects/views
yet, but I have some ideas about that.  Rule-related permissions checking
moved out of rewriter and into executor.
INITDB REQUIRED!
