      Rip out QueryTreeList structure, root and branch. Querytree · 507a0a2a
      Tom Lane authored
      lists are now plain old garden-variety Lists, allocated with palloc,
      rather than specialized expansible-array data allocated with malloc.
      This substantially simplifies their handling and eliminates several
      sources of memory leakage.
      Several basic types of erroneous queries (syntax error, attempt to
      insert a duplicate key into a unique index) now demonstrably leak
      zero bytes per query.
