Log message:
    Phase 2 of read-only-plans project: restructure expression-tree nodes
    so that all executable expression nodes inherit from a common supertype
    Expr.  This is somewhat of an exercise in code purity rather than any
    real functional advance, but getting rid of the extra Oper or Func node
    formerly used in each operator or function call should provide at least
    a little space and speed improvement.
    initdb forced by changes in stored-rules representation.
