Hi,
the change that made psycopg2.connect a module-level Python function
rather than a function exposed from a C module turned ou to be
backwards-incompatible.
Attached is a small snippet that works well with psycopg2 2.4.2 and
tracebacks with "TypeError: argument 1 must be string, not C" with 2.4.3.
The potential for actual breakage is very small, but I wanted to report
it in case someone hits it like I did and perhaps to discuss whether the
fix I applied is correct.
This was first reported to me by users of txpostgres, which got broken
by the connect() changes. The fix I applied is:

Cheers,
