Обсуждение: Intel x64 vs AMD x64 pgdata
Hey folks, Asking here since it may deal with clever things such as alignment and or binary reps. I'm migrating from some opterons to some xeons (E5345) both are running x86_64. At first I figured I'd need to dump & load my data, which will be painful. But on a whim I made a test db on the opteron, copied it over (tar) and it fired up and worked fine on the xeon. Seeing the success of this, I took our PITR backup and restored it properly, and everything seems to be functioning correctly from my tests. Is there anything I should be weary of doing this? I'd figure any alignment or other issues would have bitten me in my testing or PG would simply refuse to start. btw, the version in question is 8.2.5 thanks guys! -- Jeff Trout <jeff@jefftrout.com> http://www.dellsmartexitin.com/ http://www.stuarthamm.net/

Sure, those are the same architecture as far as PG is concerned.

x86_64 is x86_64, regardless of intel or amd.

Not exactly, ask kernel guys ;-). But for user space yes.
