-- pg_tre 1.6.1 -> 1.7.0 upgrade.
--
-- No SQL-catalog changes; same on-disk format (v6); no REINDEX
-- required.  1.7.0 makes index builds cancellable (interruptible
-- sort + CHECK_FOR_INTERRUPTS in the posting-build loops), adds the
-- pg_tre.build_max_entries_mb ceiling so an oversized build fails
-- cleanly instead of OOM-killing the server, and documents that
-- CREATE INDEX CONCURRENTLY / REINDEX CONCURRENTLY are supported and
-- verified (use them to avoid the heavy build lock).
--
--     ALTER EXTENSION pg_tre UPDATE TO '1.7.0';
--
-- after installing the new shared library.  Intentionally empty.
