Certainly not, and I hope no one has gotten the impression that there's 
anything "official" being recognized about psycopg happening here 
because it hasn't.  Anointing a "one true driver" (a phrase that seems 
to keep popping up in external discussions of this topic) isn't the sort 
of thing the PostgreSQL core does.  And all that happens to people who 
ignore what I tell them to do is that they receive a steady stream of 
long, sarcastic e-mails for a while afterwards.

I just updated 
http://wiki.postgresql.org/wiki/Python_PostgreSQL_Driver_TODO to reflect 
a few corrections I noted while researching (everybody else is welcome 
to edit that page too you know), and to include some of the recent 
feedback showing up on this list.

I know I was just looking for a Python driver that is compatible with 
the apps I most often run into, documented well enough that I can write 
my own if I feel like it, fast enough, and free enough that I can deploy 
the result wherever I want.  That seemed similar to the priorities other 
people who had an opinion here suggested too.  Pragmatically, psycopg2 
just seemed to have the shortest path toward being something useful to 
the largest userbase in that sort of context, and we've unofficially 
rolled down that path a bit.

This rabble-rousing seems to have nudged both development communities 
toward being more closely aligned in the future in a couple of ways, 
which is great, but I wouldn't read much more into things than that.  
Other projects will continue to grow and shrink, and the pure Python 
ones in particular continue to be quite valuable because they fill a 
niche that psycopg2 doesn't target at all.  I'd sure like to see all 
three of those projects merge into one big one though.  My bet has to be 
on pg8000, since it has the perfect license, supports all the necessary 
Python versions, and it's been around long enough (almost two years) 
that support for it is already in the latest SQLAlchemy beta.

We seem to have revitalized discussion around modernizing PyGreSQL too, 
so I wouldn't discount that one completely yet either.  For those who 
feel a true BSD license is vital, I direct you toward 
http://mailman.vex.net/pipermail/pygresql/2010-February/002315.html to 
learn more about what direction they could use some help in going.  But 
whatever you do, don't start another project instead.
