Yes, I would. 7.4 was the first release to include support for proper spinlocks on AMD64. (From a Redhat POV, it would probably be a good idea to patch 7.3 to include the relatively trivial changes needed for decent AMD64 performance, assuming that shipping a more recent version of PG with ES isn't an option.) -Neil
