private boolean canRewriteExtract(RexNode operand) {
  // We rely on timeUnits being sorted (so YEAR comes before MONTH
  // before HOUR) and unique. If we have seen a predicate on YEAR,
  // operandRanges will not be empty. This checks whether we can rewrite
  // the "extract" condition. For example, in the condition
  //
  //   extract(MONTH from time) = someValue
  //   OR extract(YEAR from time) = someValue
  //
  // we cannot rewrite extract on MONTH.
