Hm. Do you have an especially long intra-checkpoint interval set in
postgresql.conf? I'd expect that if you'd done anything to the db and
then waited at least a checkpoint interval (or done a manual CHECKPOINT)
before killing the postmaster, you'd find a non-shutdown checkpoint
record. That's what I get anyway.

Yeah, that would be the normal symptom of reaching the end of the log.

It's debug, and so labeled.
Possibly we need more elog levels than we have --- the stuff that comes
out at startup is not all of the same urgency, but DEBUG is the only
elog level we can use for it, really...
