[postgresql] [bug] [py3k] Fixed bug in PostgreSQL COLLATE / ARRAY adjustment first introduced
in #4006 where new behaviors in Python 3.7 regular expressions
caused the fix to fail.
[mysql] [bug] MySQL dialects now query the server version using
explicitly to the server to ensure we are getting the correct version
information back. Proxy servers like MaxScale interfere with the value
that is passed to the DBAPI's connection.server_version value so this
is no longer reliable.
