示例1: GPOS_NEW
//---------------------------------------------------------------------------
// @function:
// CConstraintConjunction::PcnstrCopyWithRemappedColumns
//
// @doc:
// Return a copy of the constraint with remapped columns. If must_exist is
// set to true, then every column reference in this constraint must be in
// the hashmap in order to be replace. Otherwise, some columns may not be
// in the mapping, and hence will not be replaced
