Create an Postgresql.DefaultPrivileges Resource I Need These Two Commands: GRANT SELECT on ALL TABLES in SCHEMA Public to Krzysztof; ALTER DEFAULT PRIVILEGES in SCHEMA Public GRANT SELECT on TABLES to Krzyszto

In this solution, we will create a Pulumi program to manage PostgreSQL default privileges using the postgresql.DefaultPrivileges resource. This will allow us to grant SELECT privileges on all tables in the public schema to a user named krzysztof and set the default privileges for future tables in the same schema.

Step-by-Step Explanation

1. Install Pulumi and PostgreSQL Provider: Ensure you have Pulumi installed and set up. Install the PostgreSQL provider using npm install @pulumi/postgresql.
2. Create Pulumi Program: Initialize a new Pulumi project and create a TypeScript file (e.g., index.ts).
3. Configure PostgreSQL Provider: Set up the PostgreSQL provider with the necessary connection details.
4. Create DefaultPrivileges Resource: Define the postgresql.DefaultPrivileges resource to grant the required privileges.
5. Run Pulumi Up: Deploy the changes using pulumi up.

Summary

By following these steps, you will be able to manage PostgreSQL default privileges using Pulumi. This approach ensures that the necessary privileges are granted to the user krzysztof for both existing and future tables in the public schema.

Full Code Example

import * as pulumi from "@pulumi/pulumi";
import * as postgresql from "@pulumi/postgresql";

// Configure the PostgreSQL provider
const provider = new postgresql.Provider("postgresql", {
    host: "localhost",
    port: 5432,
    username: "your_db_user",
    password: "your_db_password",
    database: "your_db_name",
});

// Create the DefaultPrivileges resource to grant SELECT privileges on all tables in the public schema to user 'krzysztof'
const defaultPrivileges = new postgresql.DefaultPrivileges("defaultPrivileges", {
    objectType: "table",
    privileges: ["SELECT"],
    role: "krzysztof",
    schema: "public",
    database: "your_db_name",
    owner: "your_db_user",
}, { provider });

// Export the ID of the default privileges resource
export const defaultPrivilegesId = defaultPrivileges.id;
