If you don't use PubSub to store persistent data (normal instant
messaging clients usually don't), a quick'n'dirty fix would be to just
ditch the PubSub tables and have ejabberd re-create them:

1) Stop ejabberd.
2) mv /opt/ejabberd-17.01/database/ejabberd at localhost/pubsub* /tmp
3) Start ejabberd.
