The dialect to use is also automatically detected based on the current `DataSource`, but
you can set `spring.jpa.database` yourself if you want to be explicit and bypass that
check on startup.
NOTE: Specifying a `database` leads to the configuration of a well-defined Hibernate
dialect. Several databases have more than one `Dialect`, and this may not suit your needs.

figure things out or set the dialect by setting the `spring.jpa.database-platform`
property.
The dialect to use is detected by the JPA provider. If you prefer to set the dialect
yourself, set the `spring.jpa.database-platform` property.
The most common options to set are shown in the following example:
