notified on shutdown

This is not a bug report. I have a question.

How can my app get notified when postgres goes offline or crashes ?
Is there any such functionality? From what I can understand so far, I can have some callbacks when connections are opened and acquired (init and setup) but I cannot know when postgres goes offline.

Thank you

Start by reviewing asyncpg's connection lifecycle callbacks and PostgreSQL offline or crash behavior described in the issue. A useful outcome would be a decided notification approach or a clearly documented limitation, but no implementation entry point or test is named.
