RE: Use of "long" in incremental sort code

Hi

Found one more place needed to be changed(long -> int64).

Also changed the output for int64 data(Debug mode on & define EXEC_SORTDEBUG )

And, maybe there's a typo in " src\backend\executor\nodeIncrementalSort.c" as below.
Obviously, the ">=" is meaningless, right?

-        SO1_printf("Sorting presorted prefix tuplesort with >= %ld tuples\n", nTuples);
+        SO1_printf("Sorting presorted prefix tuplesort with %ld tuples\n", nTuples);

Please take a check at the attached patch file.
