Well PY_VISIT was in use with 2.0.8 as well (there was a compatibility
macro when it is not available).

I think there might be quite a lot people out there who might using it.
Essentially everyone who has Zope <=2.8 instances in production (and
using postgres connections). 

Also i found a compatibility issue with ZPsycopDA. The version check for
ALLOWED_PSYCOPG_VERSIONS does not work with any version higher than
2.0.9 (as psycopg2.__version__[:5] is too short for anything later).
"2.0.11"[:5] == "2.0.1"

I think it is absolutely ok to drop python 2.3 support (as of course its
very old). But this should not be done with a minor release or without
notification in the change logs.
