Re: [I] Source NACK breaker stops non-replayable sources, and the stop is unobservable [iggy]

   PostgreSQL send-failure case discussed in #3957:
   
   The PostgreSQL source retains staged cleanup or replication-slot advancement after an Iggy send failure so the batch can be replayed safely. However, five consecutive send-failure NACKs still stop the source permanently, requiring a manual restart even though recovery is possible. This supports distinguishing transient send failures or making the NACK breaker configurable per connector.
