There are small typos in: - doc/src/faq.rst - psycopg/cursor_type.c - psycopg/xid_type.c - scripts/make_errorcodes.py - scripts/make_errors.py - tests/dbapi20.py - tests/test_connection.py Fixes: - Should read `publicly` rather than `publically`. - Should read `unicode` rather than `uniconde`. - Should read `supposed` rather than `suppsed`. - Should read `something` rather than `somenthing`. - Should read `portable` rather than `portible`. - Should read `exhausted` rather than `exausted`. - Should read `compliance` rather than `compiliance`.

# DDL even more portable (this will be reversed if it causes more problems)

# nothing

This implementation tests Gadfly, but the TestCase

is structured so that other self.drivers can subclass this

expected that this TestCase may be expanded in the future

class mytest(dbapi20.DatabaseAPI20Test):

confuse the unit tester - just 'from . import dbapi20'.
