-- pg_turbovec 1.29.2 -> 1.29.3
--
-- Runtime-hardening patch: no wire-format change (stays v7), no SQL surface
-- change, no REINDEX. sparsevec densify OOM guards + scan-path corrupt-slot
-- ERROR (not panic) + VACUUM interrupt poll. The fix lives entirely in the
-- extension binary; this upgrade script is intentionally empty but MUST
-- exist so `ALTER EXTENSION pg_turbovec UPDATE TO '1.29.3'` succeeds and the
-- version is recorded.
