Also known as pyPgSQL, my personal choice, mostly because it is BSD
licensed, compiles easily on Win32 and is fairly DB-API compliant.
Authors have been fairly responsive to my bug reports over the months.

One of the more popular ones. Last I heard it was still GPL licensed,
though apparently there's some plans to make it BSD licensed as it
merges with pygresql. IIRC it has a very strong Zope DA.

GPL-licensed AFAIK, apparently designed to be more thread-safe and
efficient than "the others". Again, popular. Again, I seem to recall
that it has a strong Zope DA.

Ancient code (maintained by my business partner incidentally) which
predates the DB-API (though is still maintained), intention is to merge
the project with PoPy. BSD-style License (it's part of the postgresql
tree). This is *not* a DB-API module, and I personally would *not*
suggest using it in new code unless you desperately need the special
features of the "classic" API it provides... and even then...

Mostly licensing issues, thread safety and efficiency are the
differentiators AFAICS.
Good luck,
