-- pg_turbovec upgrade 2.15.0 -> 2.15.1
-- Run automatically by `ALTER EXTENSION pg_turbovec UPDATE TO '2.15.1';`.
--
-- No new or changed SQL objects. v2.15.1 fixes a flat-index .tvim
-- duplicate-id corruption left by a CANCELLED VACUUM (the swap-remove now
-- lowers n_vectors atomically with each slot move). Library-only; no wire
-- change (stays v8), scoring bit-identical, no REINDEX required by the
-- upgrade. An index already corrupted by the bug is repaired by a plain
-- `REINDEX INDEX <name>;`. Intentionally empty apart from this comment.
