has_database_privilege is true?

Hi,

I create a role "test" and it can't (intentionally) login. But why does has_database_privilege() return true if "test"
can'tconnect to the cluster and can't use any database? Is this a bug or am I doing something strange here? Any ideas? 

I'm on PostgreSQL 12.4.

Cheers,
Paul
