Use it to teach MySQL to set `mysql_auto_reconnect` to false, to keep MySQL's auto-reconnection feature from interfering with DBIx::Connector's auto-reconnection functionality in `fixup` mode. Thanks to Karen Etheridge and Peter Rabbitson for the report.
It's important for the execution methods that the database handle raise exceptions on errors so that they can be properly handled. This is especially true for C<txn()> to get automatic rollback on failure. So set `RaiseError` to true if neither it nor `HandleError` has been specified. And document how important it is that these attributes be set correctly. While at it, document that DBIx::Connector also chagnes the default value of `AutoInactiveDestroy`.
