From 3a94e789f5c9537d804210be3cb26f7fb08e3b9e Mon Sep 17 00:00:00 2001

Subject: 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!
