Some thinking on this made me realize where you could get into this 
situation. Namely if you are using psycopg2 compiled against an older 
version of libpq that you then use to connect to a newer version of the 
server that is using an authentication method that the libpq version 
does not know about. This however is a generic issue of mismatched 
libraries and not unique to psycopg2.
