-- pg_tre 3.0.1 -> 3.0.2 upgrade.
--
-- Packaging + documentation release: the Nix flake now exposes the
-- built extension per PostgreSQL major (nix build .#pg17 / .#pg18),
-- mirroring pg_fts, so it can be overlaid into an official postgres:NN
-- image.  No C, WAL, SQL-surface, or on-disk-format change; this upgrade
-- is a pure version bump -- no REINDEX, no DDL.
