Hi David,
Taken from [1], for setting the password for the engine user.
su - postgres
psql
postgres=# create role engine with login encrypted password 'password';

You can set the password for the postgres with 'sudo passwd postgres'
(Alghout the password should be postgres)

For unlocking the disk, follow the example here [2]
$ PGPASSWORD=xxxxxx ./unlock_entity.sh -t disk -q
