During the initial setup of the MusicBrainz DB, I loaded the dump (mbdump and mbdump-derived) data into the tables and then I tried to create the necessary objects but some of the check constraints failed.

ALTER TABLE release
  ADD CONSTRAINT control_for_whitespace CHECK (controlled_for_whitespace(name)),
  ADD CONSTRAINT only_non_empty CHECK (name != '');
 --SQL Error [23514]: ERROR: check constraint "control_for_whitespace" of relation "release" is violated by some row

ALTER TABLE release_group
  ADD CONSTRAINT control_for_whitespace CHECK (controlled_for_whitespace(name)),
  ADD CONSTRAINT only_non_empty CHECK (name != '');
 --SQL Error [23514]: ERROR: check constraint "control_for_whitespace" of relation "release_group" is violated by some row

ALTER TABLE track
  ADD CONSTRAINT control_for_whitespace CHECK (controlled_for_whitespace(name)),
  ADD CONSTRAINT only_non_empty CHECK (name != '');
 --SQL Error [23514]: ERROR: check constraint "control_for_whitespace" of relation "track" is violated by some row

ALTER TABLE recording
  ADD CONSTRAINT control_for_whitespace CHECK (controlled_for_whitespace(name)),
  ADD CONSTRAINT only_non_empty CHECK (name != '');
 --SQL Error [23514]: ERROR: check constraint "control_for_whitespace" of relation "recording" is violated by some row

ALTER TABLE work
  ADD CONSTRAINT control_for_whitespace CHECK (controlled_for_whitespace(name)),
  ADD CONSTRAINT only_non_empty CHECK (name != '');
 --SQL Error [23514]: ERROR: check constraint "control_for_whitespace" of relation "work" is violated by some row

How should I move forward?
