well actually yes and no 

PoPy was started by Federico and Michele at their job.  When they left,
they decided to rewrite PoPy with the lessons learned, and so was born
pyscopg.  Gerhard was (iirc) a psycopg user who decided he wanted 1)
asyncronous parts of libpq which were not in psycopg, and 2) wanted a
pure python module (psycopg is all C).  And so PygreSQL bloomed.

PygreSQL works in Windows, psycopg may or may not;
PygreSQL has a pure python interface, psycopg's C code is very readable;
psycopg gives you the option of having serialized or nonserialized
cursors, i don't believe PygreSQL has that feature;
PygreSQL supports asynchronous features of libpq, psycopg 1.1x versions
have that support now;

both are excellent modules.

re: psycopg license:  Federico and I had a conversation about this 2(?)
years ago.  He does not consider applications that use psycopg to be
derivative works.

in spirit of full disclosure.. i help Federico maintain psycopg.
