/* Set MySQL server SQL modes to behave as closely as possible to Oracle and
* PostgreSQL. Note that the ONLY_FULL_GROUP_BY mode is left on purpose because
* MySQL requires you to specify all non-aggregate columns in the group by list
* even if the query is grouped by the master table's primary key which is valid
* ANSI SQL though. Further in that case the query plan would suffer if you add more
* columns to the group by list.
* @TODO(#4462): NO_ZERO_IN_DATE has been added with MySQL version 5.1.11. Is it
* safe to pass this option since (older) versions ignore modes unknown by this time?
