-- pg_turbovec 2.8.1 -> 2.8.2
-- Documentation-only: clarifies that WITH (lists = N) is supported for EVERY
-- bit_width (a production user read the "1-bit-only" benchmark result as a
-- support restriction), and adds an operator decision guide for whether to
-- enable IVF, with a recipe for measuring it on your own data.
-- Binary byte-identical to 2.8.1. No wire change (v8), no REINDEX.
-- Intentionally empty but MUST exist so ALTER EXTENSION ... UPDATE succeeds.
