I strongly agree here only if we can prove there is a benefit. I think it would be silly of us if some OS supported SnazzyFeatureC that was able to speed up PG by a large percentage (hopefully, in a rather non-invasive way in the code). But, I do see the problem here with bloat and PG being radically different platform to platform. I suppose we could dictate that at least N os's had to have it.. or perhaps supply it has contrib/ patches.... Something to think about. I'd be interested in tinkering with this, but I'm more interested at the moment of why (with proof, not antecdotal) Solaris is so much slower than Linux and what we cna do about this. We're looking to move a rather large Informix db to PG and ops has reservations about ditching Sun hardware. -- Jeff Trout <[EMAIL PROTECTED]> http://www.jefftrout.com/ http://www.stuarthamm.net/ ---------------------------(end of broadcast)--------------------------- TIP 9: the planner will ignore your desire to choose an index scan if your joining column's datatypes do not match
