This seems a huge amount of work to optimize *one* benchmark. If it weren't so narrowly focused on the properties of a particular benchmark (mostly UPDATE, mostly a few columns in wide tuples), I'd get more excited. The extra time spent holding exclusive lock on the page doesn't sound attractive either ... regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 1: if posting/reading through Usenet, please send an appropriate subscribe-nomail command to [EMAIL PROTECTED] so that your message can get through to the mailing list cleanly
