-- pg_turbovec v2.12.1
--
-- PATCH: builds again under Nix / nixpkgs' rustc (LLVM 21) -- flake vendoring
-- hash key fixed (turbovec-1.1.2) and turbovec fork carry #5 emits vpdpbusd via
-- inline asm on LLVM < 22; turbovec 1.1.1 -> 1.1.2 (staged-search recall fix on
-- corpora with a strong shared direction, upstream #562); pgrx 0.19.1 -> 0.19.3.
--
-- No SQL-surface change, no GUC change, no wire-format change
-- (MetaPageData::version stays 8), index bytes unchanged, so NO REINDEX.
-- `ALTER EXTENSION pg_turbovec UPDATE TO '2.12.1'` plus reconnecting is
-- sufficient.
