I think the best short term chance for 64 bit postgresql on windows is the upcoming SUA, aka Interix with the beefed up posix kernel personality that is coming out with the new server. The old interix had a full gnu toolset capable of compiling postgres. The neatest part was that they made it easy to swap out intel, ms, and gcc compilers.
Yeah, that might well be the best long-term solution.
That being said, from what I’m hearing it may be moot because it’s probably best to run postgres as 32 bit on a 64 bit operating system performance wise.
Oh? why's that then?
