Sometimes I'm asked to review a Django project's performance. The most
typical issues are probably N+1 selects and wasting time creating
connections.
I propose encouraging setting `CONN_MAX_AGE` to a non-zero value by:
- Setting `CONN_MAX_AGE` to `None` or a reasonably high value in the
generated `settings.py` - but keeping the default as-is for compatibility.
- Adding a deployment level system check to guard against a zero value.
Anyone who needs this to be `0` can easily change it and silence the
system check, but I think most projects will benefit from this.
