This seems like a good cleanup, but:
- It makes no sense to put a macro definition in a header file when
the corresponding structure definition is private to a specific .c
file.
- You failed to update the header comment for PartitionBoundInfoData
which mentions the has_null flag.
- The comment for null_index also seems like it should be updated to
mention that -1 is the sentinel value in general, not just for
range-partitioned tables.
I committed this with fixes for those issues, plus I renamed the macro
to partition_bound_accepts_nulls, which I think is more clear.
