Hi
I am sending updated patch. It should to solve almost all Giles's and
Peter's objections.
I am not happy so executor access values of variables directly. It is most
simple implementation - and I hope so it is good enough, but now the access
to variables is too volatile. But it is works good enough for usability
testing.
I am thinking about some cache of used variables in ExprContext, so the
variable in one ExprContext will look like stable - more like PLpgSQL
variables.
Regards
Pavel
