Snow Leopard should be running with Python 2.6 so something is wrong with  
your system if Python 2.5 is your python. Apple's versions of Python 2.4  
and 2.5 do not work properly on Snow Leopard if you upgraded and 2.6 was a  
botched job and is already out of date.

My advice is that you install MacPorts [1] and use it to install Python  
and most packages for you:

sudo port install py25-psycopg2 py26-psycopg2 python_select

(even py27-psycopg2 works fine if you can get Python 2.7 installed)

Alternatively, install Python for Mac OS from the Python homepage but I  
prefer using ports to keep up to date.
