I meant for anything that doesn't have an IF [NOT] EXISTS, including
cases where such a clause wouldn't be possible. For instance if you
have to provide an upgrade script that change a column datatype.
As Adrian mentioned, sqitch should provide a sensible framework for
that, but there may be similar tools more suitable for your
environment if you're already using other frameworks.
