Question

How to provide access to a public scheme in PostgreSQL 15 or 16 using terraform?

PostgreSQL has brought the changes related to a public scheme.

  • Remove PUBLIC creation permission on the public schema (Noah Misch)
  • Change the owner of the public schema to be the new pg_database_owner role (Noah Misch)

The question is how to create a user using resource digitalocean_database_user to be belong to the new role?

I have tested on 16 and have not found such role.

Hey!

Any new users created with digitalocean_database_user resource or manually via the DigitalOcean Control Panel, will always have normal role, only the default user that comes with database cluster creation has primary role.

Additional permissions must be managed manually.

You can either do it manually as described here:

https://docs.digitalocean.com/products/databases/postgresql/how-to/modify-user-privileges/

Or you could use the Postgres Terraform provider instead:

https://registry.terraform.io/providers/cyrilgdn/postgresql/latest/docs

Hope that this helps!
