Re: [TCWG CI] Failure after basepoints/gcc-13-3596-ge7310e24b1c: Make ranger vrp1 default.

[Andrew MacLeod]

This problem should be resolved with:

commit 6fd485d15c1a2c427c39bcd45e03bed8cde689e6
Author: Andrew MacLeod <amacleod@redhat.com>
Date:   Wed Nov 2 21:37:49 2022 -0400

     Update range query cache when a statement is updated.
