Review Comment:
This is default now. There's no need for users to set it, I guess.
I suppose we may want to give an example for Data Source properties instead
:thinking: ... for a local PostgreSQL server, perhaps?

Review Comment:
From my POV `application.properties` is not the best place for user-level
settings. In binary distributions the default one is embedded into jar files
and not directly accessible, while the optional local file is relative to the
current directory, which is prone to runtime mistakes.
I'd suggest using java `-D` options or env. variables in user-facing docs.

The link is still for "eclipselink"... Is that intentional?

Review Comment:
Is schema creation happening in normal runtime or only when bootstrapping (I
think the latter is the right approach).
