Commits

  1. Force "restrict" not to be used when compiling with xlc.

  2. Rely on sizeof(typename) rather than sizeof(variable) in pqformat.h.

  3. Use C99 restrict via pg_restrict, rather than restrict directly.

  4. Improve performance of SendRowDescriptionMessage.

  5. Partially flatten struct tupleDesc so that it can be used in DSM.

  6. Remove useless duplicate inclusions of system header files.
