36003	Add `connection_closed` or `pre_connection_closed` and `post_connection_closed` signals	Tomasz Wójcik	Tomasz Wójcik	"Currently I'm facing an issue with stale DB connections. It's probably related to my setup. Having `connection_closed` signal would simplify my debugging process.

Since 2009, there's `connection_created` signal.

I'd like to create a `connection_closed` signal and connect it here

https://github.com/django/django/blob/6f38697f90a14f1450a71c1e40aea0f5df7dca86/django/db/backends/base/base.py#L314

This way the connection can be accessed right before closing it.

I'd be happy to implement it. Let me know what you think.

I'm also open to `pre_connection_closed` and `post_connection_closed`. Even though not many people will ever use it, I can imagine wanting both in different cases."	New feature	assigned	Database layer (models, ORM)	dev	Normal				Unreviewed	0	0	0	0	1	0
