Count SP-GiST index scans in pg_stat statistics. Somehow, spgist overlooked the need to call pgstat_count_index_scan(). Hence, pg_stat_all_indexes.idx_scan and equivalent columns never became nonzero for an SP-GiST index, although the related per-tuple counters worked fine.
This fix works a bit differently from other index AMs, in that the counter increment occurs in spgrescan not spggettuple/spggetbitmap. It looks like this won't make the user-visible semantics noticeably different, so I won't go to the trouble of introducing an is-this- the-first-call flag just to make the counter bumps happen in the same places. Per bug #17163 from Christian Quest. Back-patch to all supported versions.
