I should mention on this one, I was working with 3.2.0 and having an incredibly 
difficult time getting it working, probably ended up with a much more complex 
set up (PGBouncer) than needed, because there was apparently a bug in 3.2.0 
related to this. Moving to 3.2.1 works super smoothly (still using PGBouncer)
