docs: Query the segment database for this flag's active segments.
  
          This method assumes all of the metadata for each flag have been
          filled. Minimally, the following attributes must be filled
  
          .. autosummary::
  
             ~DataQualityFlag.name
             ~DataQualityFlag.known
  
          Segments will be fetched from the database, with any
          :attr:`~DataQualityFlag.padding` added on-the-fly.
  
          This `DataQualityFlag` will be modified in-place.
  
          Parameters
          ----------
          source : `str`
              source of segments for this flag. This must be
              either a URL for a segment database or a path to a file on disk.
  
          segments : `SegmentList`, optional
              a list of segments during which to query, if not given,
              existing known segments for this flag will be used.
  
          pad : `bool`, optional, default: `True`
              apply the `~DataQualityFlag.padding` associated with this
              flag, default: `True`.
  
          **kwargs
              any other keyword arguments to be passed to

          Returns
          -------
          self : `DataQualityFlag`
              a reference to this flag
