Hi all

I am looking on this patch. I can confirm 10-15% speedup - and the idea
behind this patch looks well.

This patch
http://www.postgresql.org/message-id/4146.1425872254@sss.pgh.pa.us contains
two parts

a) relative large refactoring

b) support for resettable fields in param_list instead total reset

I believe it should be in two separate patches. Refactoring is trivial and
there is no any possible objection.

Regards

Pavel
