[PATCHES] Re: [HACKERS] choose_bitmap_and again (was Re: [PERFORM] Strangely Variable Query Performance)
Can you find any cases where it makes a worse choice than before? Another thing to pay attention to is whether the planning time gets noticeably worse. If we can't find any cases where it loses badly on those measures, I'll feel comfortable in applying it... I'll see what I can find -- I'll let you know on Monday if I can find any queries that perform worse. My tests so far have shown equivalent or better performance so far but I've only done sort of a survey so far ... I've got plenty of special cases to test that should put this through the paces.

Re: [PATCHES] build/install xml2 when configured with libxml
Andrew Dunstan wrote: I don't think it should go away until we provide for equivalents in core, at least optionally. Well, if we're going to make libxslt an explicit thing, then it'd be trivial to add an xslt transformation function into the core, and then I think we can claim equivalent support. But we'll have to check the details, of course. I have been thinking, however, that I don't want to add more and more library dependencies into the server. libxml2 was necessary to some extent. But xslt functionality could easily be provided as a module. This would be easy to do and might be useful even for 8.3. But I don't really know how to label that. Having a contrib/xslt alongside contrib/xml2 would probably be confusing.
