dbconfig-no-thanks 2.0.4 (amd64 binary) in ubuntu xenial

 If a package relies on the dbconfig-common framework for database setup and
 maintenance, installing dbconfig-no-thanks instead of one of dbconfig's
 database-specific packages will block this function. It is intended for cases
 where the system administrator desires or requires full control of the
 database or where dbconfig-common makes bad choices, and typically leaves
 the depending packages non-functional until manually configured.
