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!
