By the way, this is, given that the added check in init_toast_snapshot
is valid, a long-standing "bug", which at least back to 12.

I'm not sure what to do for this.

1. ignore the check for certain cases?

2. apply any fix only to master and call it a day.  14 and earlier
  doesn't have the assertion check so they don't complain.

3. apply a fix to all affected versions.

regards.
