It starts an asynchronous infinite task that checks the connectivity with the database. In case of error, the postgres_healthcheck task tries to reconnect for a while, and if it determines that the connection cannot be resumed, then it invokes a callback indicating that situation. For the case of the `wakunode2` app, this callback quits the application itself and adds a log trace indicating the connectivity issue with the database.
