Log Message: ----------- Extend the MinimalTuple concept to tuplesort.c, thereby reducing the per-tuple space overhead for sorts in memory. I chose to replace the previous patch that tried to write out the bare minimum amount of data when sorting on disk; instead, just dump the MinimalTuples as-is. This wastes 3 to 10 bytes per tuple depending on architecture and null-bitmap length, but the simplification in the writetup/readtup routines seems worth it.
