I wrote the patch that introduced RELOPT_KIND_PARTITIONED. Yes, it
was added as a stub relopt_kind to eventually apply to reloptions that
could be sensibly applied to partitioned tables. We never got around
to working on making the existing reloptions relevant to partitioned
tables, nor did we add any new partitioned table-specific reloptions,
so it remained an unused relopt_kind.
IIUC, this patch invents PartitionedRelOptions as the binary
representation for future RELOPT_KIND_PARTITIONED parameters. As long
as others are on board with using different *Options structs for
different object kinds, I see no problem with this idea.
Thanks,
Amit
