    Uh oh - Aggregates require a group by clause in the select.
    This is correctly copied into the query action in the views
    pg_rewrite entry. But the rewrite handler doesn't insert it
    into the parsetree. Thus a wrong execution plan in built.

    I'll try some things, but expect to get into trouble if the
    select from the view contains it's own grouping clauses.

    Let's see.

	Arrrg

	Please add the line 

		if (!bootstrap)

	above the 
		
		InitLocalInvalidateData();

	in postinit.c manually. Calling it in bootstrap mode causes
	postgres to dump core. With that test everything is fine.


Thanks, Jan

There is another way of VIEW implementation: put VIEW' query
as subselect into FROM clause. The last feature is not implemented
yet. It's just a thought...
