This is not supported by all databases/versions. We could implement
this for those that support it but we will soon have another problem:
what if the table exists but from some older version of our application?
To solve this you can use ODB's database schema evolution support (Chapter
13) which also takes care of properly detecting whether the schema does
not yet exist.
