Replace/alter the object if it already exists, but fail if it does not
exist.

The complete set of variants is:

- object does not exist:
   - proceed (normal CREATE)   - error (my above description)

- object exists:
   - replace (CREATE OR REPLACE)   - skip (CREATE IF NOT EXISTS)   - error (normal CREATE)
