 A supported SQL database
        Currently supported:  MySQL 5.7 with InnoDB support
                          MariaDB 10.2 or later with InnoDB support
                          Postgres 9.5 or later
                          Oracle 12c or later
                          SQLite 3.0 or later; for testing only, no
                                       upgrade path guaranteed

It looks like MySQL 8 is actually not supported, I believe that is because “groups” became a reserved word in that version.

There is a test branch for MySQL 8 (i.e. quoted table names" but it is a TEST branch.
You can build it yourself from the git tree (specifics left as an exercise for the user).
