I cannot find a usable database user to construct the DAViCal database with, but
I may have successfully created the davical_app and davical_dba users.
You should edit your pg_hba.conf file to give permissions to the davical_app and
davical_dba users to access the database and run this script again. If you still
see this message, you will need to make sure you run the script as a user which
has full permissions to access the local PostgreSQL database.
