      Column `#{foreign_key}` on table `#{table}` does not match column `#{primary_key}` on `#{target_table}`,
      which has type `#{primary_key_column.sql_type}`.
      To resolve this issue, change the type of the `#{foreign_key}` column on `#{table}` to be :#{type}.
      (For example `t.#{type} :#{foreign_key}`).
    EOM
  else
    msg = <<~EOM.squish
      There is a mismatch between the foreign key and primary key column types.
      Verify that the foreign key column type and the primary key of the associated table match types.
