services.postgresql.ensureUsers.*.ensureClauses.superuser

Grants the user, created by the ensureUser attr, superuser permissions. From the postgres docs:

A database superuser bypasses all permission checks, except the right to log in. This is a dangerous privilege and should not be used carelessly; it is best to do most of your work as a role that is not a superuser. To create a new database superuser, use CREATE ROLE name SUPERUSER. You must do this as a role that is already a superuser.

Type
