Column <str> in table <str> is being altered to remove domain

  Explanation:  When you issue the DROP SCHEMA or DROP CATALOG
  statement and specify the CASCADE behavior, SQL drops all of the
  domains in that schema or catalog.  If one of the columns in a
  table outside of the schema or catalog references one of those
  domains, it is altered in such a way that it no longer depends
  on the domain being deleted.

  User Action:  None.
