PyGreSQL vs psycopg2
"PyGreSQL is written in Python only, easy to deployed but slower."
PyGreSQL contains a C-coded module, too. I haven't done speed tests, but they're not likely to be much different, as the real work will happen inside the database server.
What is the difference between these two apis?
Which one faster, reliable using Python DB API?
Upd:
I see two psql drivers for Django. The first one is psycopg2.
What is the second one? pygresql?
