Yes, I am trying to find out what message i should reply if I receive email with deadlock notification.
I understand how deadlock occurs, hot to find them in logs, prevention of deadlock(ex: oqueries in order) etc.
But since the deadlock_timeout is 1s, they don't probably hang around. So post getting an alert, not sure what to respond to them

Hi
If I receive an alert for deadlock, what should I do? Like what analysis should I do? No way to find a root cause?Under pg_locks, what I can analyse?
If you receive an error with a deadlock, the current transaction is dead. You have to decide whether to try again.
Within the error message you find a hint which other (not aborted) transaction was involved in the deadlock. So you have all the information you need to find the culprit.

I wonder what you are writing about. A
database doesn't send email notifications. That must be a feature
of some application.
So you will have to deal the the
application code or its developers.
Or is it a customer sending you a message
that some deadlock happened on their system? Still, you have to
deal with the application code or the log files of the database
system.
