-- pg_turbovec 1.28.3
--
-- Managed-PostgreSQL readiness (audit follow-up). Code + CI + docs; no
-- wire change, no SQL-surface change, no REINDEX.
--
-- * Interrupt handling (P0): CHECK_FOR_INTERRUPTS at every lock-free
--   boundary pg_turbovec controls -- each amgettuple entry, each
--   CREATE INDEX build-stage boundary, and the top of each GenericXLog
--   batch in the relfile write path -- so statement_timeout /
--   pg_cancel_backend take effect promptly. (Fine-grained polling
--   inside a single flat search() call needs a kernel block-scoring
--   API; tracked follow-up.)
-- * Portability gates (P2): scripts/drift-check.sh now fails the build
--   if a raw-WAL/raw-storage primitive appears (durability must stay
--   100% GenericXLog) or if any GUC is registered non-Userset.
-- * Docs: docs/DEPLOYING_ON_MANAGED_POSTGRES.md.
--
-- `ALTER EXTENSION pg_turbovec UPDATE TO '1.28.3';` is sufficient.
