Depending on what else you did, these files may now be orphans, but see

First of all, the bogus '31 ams-announce moderator request(s)' email is
almost certainly not coming from your current Mailman 2.1.9
installation. I have never seen a report of a case like this where the
email was not coming from some old/backup/test/whatever installation
whose cron/checkdbs was still being run.
Second, the '31' has nothing to do with data/heldmsg-* files. These
files have the messages themselves, but not the pending request
information. The data for the 'moderator request(s)' email come from
the lists/listname/request.pck file. If you want to see what's there,
you can dump it with bin/dumpdb, and you can clear it by simply
removing the file, although if you dump it first, I think you'll see
it's devoid of requests just like the admindb interface says.
As far as getting a list of what messages are pending for each list in
the form heldmsg-$listname-$msgID is concerned, there's nothing that
will give you that in a nice list, but if you go to a specific list's
request.pck file and dump it with bin/dumpdb, you'll see one entry like
'version': (0, 1)
and for each held message, entries like
id: (1, (time, sender, subject, reason, filename, msgdata))
and entries with 2 or 3 as the first item of the value which are held
subscribe and unsubscribe requests.
In the held message entries, the key, id, is the number you call
$msgID; time is the time in seconds that the message was held; sender,
subject and reason are self explanitory; filename is the name of the
held message file and msgdata is a dictionary of the message's
metadata at the time it was held.
Note that if you have any request.db files, these are residue from your
prior installation. I don't know if you did an actual upgrade of your
2.0 installation to 2.1.9, but if you did, the data from the
request,db files should have been automatically migrated to the
request.pck files by bin/update as part of the 2.1.9 install. If that
isn't what happened, then I'm not sure what you're faced with in terms
of recovering any held messages.
