Prisma/ PostgreSQL: What are are the user privileges required while using Prisma with PostgreSQL?

I am using PostgreSQL as my database along with Prisma as my ORM.It seems to be giving an issue while running the 'prisma migrate' command on the server which seems to be an issue of user database privileges not being present.What are the basic user privileges that are required for Prisma while using Postgres apart from the option of giving full admin rights?
Database user needs to have a CREATEDB privilege for using migrate commands in PostgreSQL.
Here's a reference to privileges needed for each supported database: Reference.

Postgres add user impossible

I get from customer Postgres 8.4, a very strange edition
I login with Postgres user under trust settings.
But in pgAdmin i got a lot of relations errors
I thought normally tables should goes to DB Catalogs Tables, but here DB Catalogs Tables not exists or i cant see them, all tables i see in db Schemas, and database is working as i can access it through ODBC and Postgres connector, but then i see all 2809 tables i a row without separation. It like multi tenat services, but misconfigured or not suit with pgAdmin.
From pgAdmin i cant create any user and roles, from ssh psql created user cant connect through odbc or Postgres connector, and do not appears in pgAdmin Login/Group Roles tab.
So why i cant access in pgAdmin4 Login/Group Roles tab?
Why cant create user from pgAdmin4?
Why cant access pg_catalogs from pgAdmin4?
Why user created from ssh psql cant access database from ODBC or Postgres connector? (got always table is empty)
If this is multi tenant services why it not work like expected from pgAdmin?
PgAdmin 4 version 5.6
PgAdmin4 says it supports 9.5 and newer. 8.4 is not newer than 9.5.

Django models and Postgres privileges

So I'm new at Django development and I haven't figured out how models and postgresql privileges work together.
I have a postgreql database with a schema called AUTH with all the models that Django auth creates(auth_user, auth_permission, etc). The user that I passed on DATABASES on settings.py is a user that has no SELECT, UPDATE, DELETE, etc privileges on any table on that SCHEMA (I was making some tests) but when I create any user it gets written on auth_user table on SCHEMA AUTH.
So how does postgresql privileges and Django models are put together?
Thanks

Create Postgres User with admin rights just for one database

How can I create a postgres user who has admin access only to one database but cannot inspect or interfere with other databases in the postgres instance? The use case is I'm creating a multitenant application
where each tenant gets his own database in the postgresql instance and can create schemas, tables etc and
perhaps use a few pg_tables to inspect his own database but not others.
cannot change the name of the database as it's controlled by me
EDIT: Added more constraints
That's fairly trivial:
CREATE DATABASE newdb;
GRANT CREATE ON DATABASE newdb TO newdba;
Add pg_hba.conf entries to allow newdba to connect to newdb only.

Insert records to Heroku Postgres database using a rails script

I need to update a dababase from an other database... For this I need to search in existing database if the records exists, if not add... One of the database is locally stored in my computer, and the other one is on heroku... But I don't know how to access heroku database from my computer to create the inserts and to query if I have to insert or not...
Any idea how can I do something like this?
You can connect via any DB tool, e.g. Oracle SQL Developer with Postgres JDBC connector, to a Heroku Postgres DB. The parameters are listed in the GUI of postgres.heroku.com for your instance.
