      Description

      IMPALA-3726 introduced the DEFAULT keyword. To avoid breaking applications that use "DEFAULT" as an identifier for databases, tables and columns, the non-terminal ident_or_default was introduced to replace IDENT in the parser. Moving forward, we should disallow the use of DEFAULT and remove ident_or_default. This should be a backward incompatible change.
