This was briefly scary but seems to have been limited to my psql session (no
other errors logged). Issue with catcache (?)
I realized that the backup job I'd kicked off was precluding the CLUSTER from
running, but that CLUSTER was still holding lock and stalling everything else
under the sun.
psql (10.0, server 9.6.5)
