quarkus: JDBC connection does not reset

Describe the bug

1. Having up the application, with a sqs collector, started at booting via ManagedExecutor:

 void onStart(@Observes(during = AFTER_COMPLETION) StartupEvent ev) {
        managedExecutor.execute(this::startProcessing);
    }

Somewhere down the line, I do some DB selects / inserts 2. Reset the database. Reproduced in aws cloud, but even in local, with docker postgres db container. At this step end, databse is up and ready. Accepting new connections. 3. Got stack trace

Caused by: org.postgresql.util.PSQLException: An I/O error occurred while sending to the backend.

1. App still up, receives a new sqs event, in method from step 1
2. App fails on any db interaction with following:

Expected behavior

Database connection is restored after DB is up again.

Actual behavior

Infinite failure. It recovers just after the app is restarted.
