6ed83d5famade it so tuplesorts could use a bump.c memory allocator for non-bounded sorts in order to save memory and increase performance. That commit didn't get the memory accounting correct for datum sorts and mistakenly passed 0 bytes to tuplesort_puttuple_common(). That was correct for byval types, but failed to take into account palloc'd memory for byref types. Fix by using datumGetSize() when using the bump allocator and by using GetMemoryChunkSpace() when not. Backpatch to v17, where6ed83d5fawas added.
