[9.0.0] data_checksums settings inconsistent and breaks existing code

[tuxmaster5000]

After the update to 9.0.0 my code stop working with:
Class[Postgresql::Globals]: parameter 'data_checksums' expects a value of type Undef or String, got Boolean
When I take an look in the code of the module, now the option is sometimes an boolean (for example postgresql::server::instance::initdb) and sometimes an String (for example postgresql::globals)

Thanks @tuxmaster5000! v9.0.1 is available on the forge with a fix in place for this.
