      gSel - The selectivity graph to use (if required).
      start - The starting selectivity type of the conjunct to generate.
      end - The end selectivity type of the conjunct to generate.
      source - The source variable of the conjunct.
      target - The target variable of the conjunct.
      star - True if the conjunct should have a Kleene star above it.
