Tomas Vondra 14ffaece0f amcheck: Add gin_index_check() to verify GIN index ... Adds a new function, validating two kinds of invariants on a GIN index: - parent-child consistency: Paths in a GIN graph have to contain consistent keys. Tuples on parent pages consistently include tuples from child pages; parent tuples do not require any adjustments. - balanced-tree / graph: Each internal page has at least one downlink, and can reference either only leaf pages or only internal pages. The GIN verification is based on work by Grigory Kryachko, reworked by Heikki Linnakangas and with various improvements by Andrey Borodin. Investigation and fixes for multiple bugs by Kirill Reshke.
