FWIW, the systemtap guys are really, really close to having a working DTrace equivalent for Linux: http://gnu.wildebeest.org/diary/2009/02/24/systemtap-09-markers-everywhere/ It's not *quite* there for our purposes https://bugzilla.redhat.com/show_bug.cgi?id=488941 but I'll be surprised if I'm not dtracing on my Fedora 10 machine before the week is out. I'm not at all convinced that we should be putting effort into a homegrown, partial substitute for DTrace. regards, tom lane -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
