### Are you willing to submit a PR?

Start with PulsarDebeziumSourcesTest.testDebeziumPostgreSqlSource and testDebeziumPostgreSqlConnect, then inspect DebeziumPostgreSqlSourceTester.setServiceContainer and PulsarCluster.startService. Reproduce the failure and investigate the Testcontainers pull of debezium/example-postgres:0.10; done means the integration test starts its container and passes consistently.
