Mike Reeves 9ebf93cc26 Empty a default and create its partition in one transaction
Telegraf never stops writing. Clearing 50 defaults with separate
TRUNCATEs left the earliest ones refilled by the time maintenance tried
to attach today's child, which then failed on the default's constraint
and aborted the whole run. Doing both under one transaction makes the
concurrent inserts wait and land in the new partition.
