SpiceDB

Hi.  We have upgraded to SpiceDB `v1.35.3` yesterday.  Since then our backup process throws:
```
12:34PM ERR terminated with errors error="error receiving relationships: rpc error: code = ResourceExhausted desc = grpc: received message larger than max (13400206 vs. 4194304)"
```
which is basically a `zed --insecure backup create /tmp/foo.dat` with `zed` being from docker image `authzed/zed:v0.21.1`.  Any idea or advice?

there should be a `--max-message-size` flag you can use on `zed` to increase that limit

I think https://github.com/authzed/zed/pull/407 is the same issue you're running into?

Yes, that's the same issue.  Glad, somebody fixed this a week ago.  😆  Adding `--max-message-size=16777216` fixed this for us.  Thanks a lot, much appreciated.

What version were you running before? This seems _unexpeted_. If you were running backups before and after the upgrade the same way, it shouldn't increase the size that dramatically, so something must have changed that have made these messages way larger.

That message is saying that you are returning a 16MB grpc message. That's _huge_. We only saw users hitting this on large schemas, but if that was your case, you would have hit it _before_ 1.35.3
