Summary: Access to SQLSTATE + memory leak

Initial Comment:
It would be nice if one had access to the postgresql
5 character "SQLSTATE" error code, to, for example,
unambiguously determine if a serialization error happened
and the transaction should be re-run.
The error code is more precise
and future-proof than a substring check on the textual
error message.

I've attached a patch to the 2.4 version of pgconnection.c.
It changes the value of a libpq.OperationalError exception
to a tuple: (sqlstate, message), a la OSError.
This fix is sufficient, but I lack the pythonic karma 
to say if it's the best way.

I added a missing PQclear() call too.
