I created a blog post about this important topic and invite you to read it. If you want to learn more about PostgreSQL, and if you happen to be interested in security in general, there is no way around encrypting client / server connections using SSL in PostgreSQL. The table will belong to the “demo” user who created the table: You're now connected to database "security" as user "demo". Once this is done, you can go ahead and create objects in this schema: Let’s connect to PostgreSQL as superuser and set USAGE CREATE = ALL permissions on the public schema. ![]() Security=# GRANT ALL ON SCHEMA public TO demo You are now connected to database "security" as user "postgres". It is now necessary to grant permissions to a user explicitly. PostgreSQL will error out and tell you that you don’t have permissions to create something inside the public schema without explicitly specifying who is allowed to do that beforehand. Check out the following listing:ĮRROR: permission denied for schema public Therefore PostgreSQL has made a major leap forward and changed this behavior. The problem with this approach is that the public schema can quickly turn into a trash can containing all kinds of used and unused tables – which is neither desirable nor recommended. The new table would simply end up in the public schema and all would be good. In PostgreSQL 14 and in prior versions, creating a table would be possible. “current_user” will return the user which is currently used. ![]() You are now connected to database "security" as user "demo". If you’re running some other tooling, reconnect using the new user: The \c command is a good way to do that if you happen to use psql. Once this is done, you can reconnect to the database. ![]() In this example, you’ll create a “demo” user, as shown in the next listing: The difference between these two options is that CREATE USER sets the LOGIN privilege directly while CREATE ROLE will set this attribute to NOLOGIN. In PostgreSQL you can create a new user using the CREATE USER or the CREATE ROLE command. It’s recommended to create separate users to run your application. This is not recommended and can lead to serious security issues. You need to be aware of how it may affect you. This is relevant because it might hurt you during application deployment. In PostgreSQL 15, a fundamental change took place which is relevant to every user who happens to work with permissions: The default permissions of the public schema have been modified.
