Postgresql & 64 Bit Opteron

Hi,

We're thinking of moving to a 64 bit platform for our database. Does
anyone have any stories of migration from 32 bit to 64 bits?
* How did it impact performance?
* Were there any gochas?
* What processors were used (any AMD Opteron's so far?)

Also what kind of performance increase could we expect if we moved from
a dual 32 bit to a quad 32 bit platform. (We are already using speedy
10,000 RPM SCSI disks in RAID configuration, with gobs of RAM.)
