What are you using for replication?

Compared to i386 how much memory is PostgreSQL and other apps using?
On another thread I asked about memory usage was told that apps in AMD64 
mode seemed to be taking twice as much memory. I would be very interesting 
in reading about PostgreSQL memory usage in FreeBSD AMD64.

I wonder other data intensive apps (ie image/audio editing) how they would 
do in Fbsd-AMD64. Also I wonder if it's an advantage only when large 
amounts of data are moving or lots of data in general. For example a busy 
news server or email server.
