Jira issue: CRDB-67640

Start with crosscluster/logical.TestLogicalReplicationExternalConnWithoutDBName and the captured test log under outputs.zip/logTestLogicalReplicationExternalConnWithoutDBName2446278749. Inspect the logical replication job progress and goroutine dump referenced by the failure, then compare the test setup for external connections without a database name. Done means the failure is explained and the test reliably reaches the expected replicated time.
