SortRel is a little under documented
- What does
SORT_DIRECTION_CLUSTERED
mean? - Let's say I was sorting by strings, how would I specify a natural sort vs alphabetical sort?
- Can we provide an example of
comparison_function_reference
? What kind of function is this? Why isn't this just an extension relation? - Are we content leaving the stability of the sort as a hint? It seems like the producer / planner might care about this.
