The reports that I've heard say that very large amounts of shared memory don't seem to offer performance improvements on Windows like you can get on Unix, so there isn't much reason to put in the (large amount of) work that would be needed to produce a native Win64 version. The exact reasons why Windows doesn't like large shmem aren't clear, at least not to me. regards, tom lane -- Sent via pgsql-general mailing list (pgsql-general@...)

True. I've definitely seen installations with 16Gb or so RAM, but they're all running with <1Gb shared_buffers. The reason they'd be interested in Win64 is really to be able to push up work_mem and maintenance_work_me. > The exact reasons why Windows doesn't like large shmem aren't clear, > at least not to me. Yeah, and also not why it doesn't always dislike it. -- Magnus Hagander Me: http://www.hagander.net/ Work: http://www.redpill-linpro.com/ -- Sent via pgsql-general mailing list (pgsql-general@...)
