   "description": "pg_lion adds the lion index access method: one compressed posting set of roaring-style containers per distinct key, serving bitmap scans for equality, IN lists and NULL tests, and a custom scan that answers count(*) with equality filters and GROUP BY from the posting sets plus the visibility map. pg_lion_citext adds an operator class for citext. pg_lion_vector adds lionvec, a nearest-neighbour index for pgvector's vector type that stays small and reads little, and that filters by lion indexes exactly.",
