Tom, I see from the CVS logs you say:
Subselects in FROM clause, per ISO syntax: FROM (SELECT ...) [AS] alias.(Don't forget that an alias is required.)
Viewsreimplemented as expandingto subselect-in-FROM.  Grouping, aggregates, DISTINCT in views actuallywork now (he says
optimistically). No UNION support in subselects/viewsyet, but I have some ideas about that.  Rule-related permissions
checkingmovedout of rewriter and into executor.
 
Does this mean the rewrite system no longer handles views?
