### Minimal reproduce step

Setting up Debezium source via example doc
https://pulsar.apache.org/docs/2.10.x/io-cdc-debezium/#example-of-postgresql

add to `debezium-postgres-source-config.yaml` heartbeat configs

```sh
heartbeat.interval.ms: 1000

Start by running the PostgreSQL Debezium source example from the 2.10.x CDC documentation with the settings in debezium-postgres-source-config.yaml. Check whether the heartbeat topic is created, the database is updated, and heartbeat events are sent; compare the observed behavior with the expected heartbeat configuration.
