Back when smoc GIN indexes were implemented, indexes did not support opclass options yet; that was added only later in PG 13.
Add an "order" parameter on the smoc_gin_ops opclass to allow picking the smoc index granularity between level 0 and 12. (Larger levels do not fit into the internal int32 datatype anymore.)
Example:
create index on sky using gin (coverage smoc_gin_ops (order = 8))
