I can reproduce the issue. The memory is being spent at only one place:

TopMemoryContext: 68688 total in 10 blocks; 2736 free (10 chunks); 65952 used
TopTransactionContext: 8192 total in 1 blocks; 4856 free (0 chunks); 3336
used
PortalMemory: 8192 total in 1 blocks; 7888 free (0 chunks); 304 used
PortalHeapMemory: 15360 total in 4 blocks; 10640 free (17 chunks); 4720
used
TupleSort: 6283429096 total in 723 blocks; 1424704 free (0 chunks);
6282004392 used

Looking.
