A room lost all its forward extremities, leading to "no create event in auth events" #7845
Description
this actually goes back to March; sadly this is the first time I've had a chance to write it up in a github issue.
Somehow a room (on the mozilla.org instance) ended up with no event_forward_extremities in the database at all, despite still having a number of local members.
The room was manually "fixed" by inserting a new row into event_forward_extremities and restarting synapse.
The only thing that looks odd is this entry in the postgres error log:
