heap_force_common() declared a boolean array indexed with an OffsetNumber for a size of MaxHeapTuplesPerPage. OffsetNumbers are 1-based, so an input TID whose offset number equals MaxHeapTuplesPerPage wrote one byte past the end of the stack array, crashing the server. Like heapam_handler.c, this commit changes the array so as it uses a 0-based index, substracting one from the OffsetNumbers.
