I have been running Sympa backed by a Galera cluster since initial
install. I do not recall having had to do anything special to the
schemas. It just works. Not all of the tables have primary keys, true,
but it does not appear to be an issue. It possibly hurts performance,
but my installation is so small it does not matter or has no visible effect.
