- If the final chunk of a large tuple being written out to disk was
- exactly 32760 bytes, it would be corrupted due to a fencepost bug.
- This is a hazard for parallelized plans that require a tuplestore,
- such as parallel hash join. The query would typically fail later
- with corrupted-data symptoms.
