 This directory includes some integration tests, specifically with the
 CockroachDB database, which uses a PostgreSQL protocol.
 
-Tests expect that the CockroachDB binary exist, and fail without it.
-
-To download a local copy of CockroachDB:
-
-```bash
-./tools/ci_download_cockroachdb
-```
-
-This downloads a binary to `./out/cockroachdb/bin/cockoach`. If you'd like
-to use your own binary here, replace this binary with your own executable.
+These tests rely on the `crdb-harness` crate to download CockroachDB
+at a particular version.
