+%description    upgrade
+This package contains the files needed for upgrading a PostgreSQL database from
+the previous major version of PostgreSQL.
+
+Note that since pg_upgrade starts the updated server with a default config file,
+you need to set:
+  PGSETUP_PGUPGRADE_OPTIONS="-O '-c shared_preload_libraries=timescaledb'"
+before running postgresql-setup --upgrade.
+This package sets it for you at login time, but if you don't want to login again
+you can run:
+  source %{_sysconfdir}/profile.d/%{name}-upgrade.sh
