Please find the attached patch. A guc parameter named 'checkpoint_partitions' is added. This can be set to 1, 2, 4, 8, or 16. Default is 16. (It is trivial at this present, I think.) And some definitions are moved from bufmgr.h to xlog.h. It would be also trivial. Best regards. -- Takashi Horikawa NEC Corporation Knowledge Discovery Research Laboratories
