Without this step, the readonly role cannot perform any action on the objects in this schema, even if the permissions were granted for those objects. This new user does not have any permissions other than the default permissions available to the public role. In this post, I talk about some of the best practices for managing users and roles in PostgreSQL.

Introduction to PostgreSQL Variables. The PostgreSQL object-relational database system provides reliability and data integrity. In PostgreSQL every database contains the public schema by default. The master user should never be used by the application. In Oracle, a role cannot be used to log in to the database. Any users and roles that should be able to connect to the database or create objects in the public schema should be granted the permissions explicitly before revoking any permissions from the public role in the production environment. Revoking permissions from the public role impacts all existing users and roles. You can use this feature to set up a policy to automatically change the password at a certain frequency.

PostgreSQL automatically creates a schema called public for every new database. A private database link can be used only by the database link’s owner. As a database server, its primary function is to store data, securely and supporting best practices, and retrieve it later, as requested by other software applications, be it those on the same computer or those running on another computer across a network (including the Internet). By doing this, you enable greater control over password management on the client side (for example, expiry requirements and complexity requirements). This pattern is a secure schema usage pattern unless an untrusted user is the database owner or holds the CREATEROLE privilege, in which case no secure schema usage pattern exists.
