flush and reset_db manager commands are failing

Version
3.80.0

Describe the bug
When it's needed to remove all data from app's database, usually it's used a manager command like flush or reset_db, but both are returning an error when used:

❯ oci-env pulpcore-manager flush
2025-06-10 11:15:45,860 - INFO - utils.py:16 - USING OCI_ENV_PATH FROM ENV: /home/decko/dev/pulp/oci_env

You have requested a flush of the database.
This will IRREVERSIBLY DESTROY all data currently in the "pulp" database,
and return each table to an empty state.
Are you sure you want to do this?

psycopg.errors.InsufficientPrivilege: permission denied to create database

To Reproduce
1 - start pulp using your preferred way.
2 - run pulpcore-manager flush or pulpcore-manager reset_db

Expected behavior
It's expected to have the application database returned to a fresh state, without user data.

Start at the pulpcore-manager entry point and reproduce both flush and reset_db failures. Trace the Django post_migrate error involving _populate_access_policies and the PostgreSQL reset_db permission error; done means both commands can return the application database to a fresh state without these failures.
