We just pushed a new release of CockroachDB and Postgres also had a recent release with a vulnerability impacting GSS. I figured it was a good time as any to update my repos with the latest versions of Postgres and Cockroach, and thereby test that everything works.

High-Level Steps
- Start a three-node CockroachDB cluster in Docker with GSSAPI.
- Demonstrate the problem scenario.
- Verify.
