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/4146.1425872...@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
