-- pg_turbovec v1.6.1 -- bench-results-only release.
--
-- This file is a *reference mirror*. The authoritative install
-- script is generated by `cargo pgrx schema`.
--
-- v1.6.1 ships zero source-code changes. It bundles two
-- bench-results commits on top of v1.6.0:
--
--   1. Phase W validation on meh (commit 8efb89c). Confirmed
--      the v1.6.0 streaming ambuild change actually drops peak
--      RSS as designed: 121 GiB -> 22.5 GiB at 10M x 1536-d,
--      60 GiB swap -> 0 GiB swap, build time within 0.1% of
--      pre-Phase-W, warm-scan p50 unchanged.
--
--   2. Phase X RISC-V architecture comparison (commit a8fbd87).
--      First non-x86 host bring-up; pg_turbovec builds, installs,
--      and queries cleanly on RISC-V 64. 100k x 384-d synthetic
--      bench: warm p50 242.64 ms (50-q stdev 0.73 ms). Verdict:
--      arch_works.
--
-- The wire format does NOT change. The on-disk index format is
-- byte-identical to v1.6.0 and v1.5.x. There is no DDL or on-disk
-- migration required.
--
-- See docs/UPGRADING.md for the v1.6 -> v1.6 patch upgrade row
-- (no REINDEX needed). This migration file exists only so the
-- upgrade path `ALTER EXTENSION pg_turbovec UPDATE TO '1.6.1';`
-- resolves without an error. It is intentionally empty.
