There is no problem with free Linux distros handling > 4 GB of memory. The
problem is that 32 hardware must make use of some less than efficient
mechanisms to be able to address the memory.

So, try 7.4 before the memory upgrade. If you still have performance issues,
try optimising your queries. As I mentioned before, you can join the
#postgresql channel on irc.freenode.net and we can assist.
