Agreed. Better classification is nice, but it also requires more
discipline and it might not always be obvious which category something
fits in. What about an error loop resulting in:

ereport(PANIC, (errmsg_internal("ERRORDATA_STACK_SIZE exceeded")));

We'd want a core file, but I don't think we want to restart in that
case, right?

Also, can we do a change like this incrementally by updating a few
PANIC sites at a time? Is it fine to leave plain PANICs in place for
the foreseeable future, or do you want all of them to eventually move?
