PostgreSQL: Give all permissions to a user on a PostgreSQL database

## PostgreSQL: Give all permissions to a user on a PostgreSQL database 🐘💻

Are you struggling with how to give a user all the permissions on a database in PostgreSQL without making them an admin? Don't worry, we've got you covered! In this guide, we'll address common issues and provide easy solutions to help you grant all the necessary permissions to a user on a PostgreSQL database.

Let's dive into the problem at hand. You mentioned that you have separate databases for DEV and PROD on the same cluster, and you want to give a user the ability to make changes to DEV objects without allowing them to modify production objects. Here's what you've tried so far:

grant ALL on database MY_DB to group MY_GROUP;

But it seems like this command didn't grant any permissions to the user. Next, you attempted:

grant all privileges on schema MY_SCHEMA to group MY_GROUP;

This command gave you permission to create objects, but you weren't able to query or delete objects on that schema that belonged to other users. You also discovered that giving USAGE permission on MY_SCHEMA wasn't enough, as it complained about not having permissions on the table.

So, is there an easy way to grant all permissions to a user on a database? Absolutely! Here's a step-by-step solution that should work for you:

1. Connect to your PostgreSQL database using a superuser or an account with sufficient privileges.

2. Grant all privileges on the schema to your user by running the following command:

grant all on schema MY_SCHEMA to MY_USER;

1. Grant all privileges on all tables, views, and sequences within the schema to your user by executing this command:

grant all on all tables in schema MY_SCHEMA to MY_USER;
grant all on all sequences in schema MY_SCHEMA to MY_USER;
grant all on all views in schema MY_SCHEMA to MY_USER;

1. Lastly, give your user the ability to execute functions and procedures within the schema by running this command:

grant all on all functions in schema MY_SCHEMA to MY_USER;

By following these steps, you should be able to grant all the necessary permissions to your user on the specific database schema.

🔥 Pro Tip: Make sure to replace MY_DB, MY_GROUP, MY_SCHEMA, and MY_USER with the actual names of your database, group, schema, and user, respectively.

Keep in mind that the above steps are based on the assumption that your user already has the necessary privileges on the database itself. If not, you can grant them using GRANT CONNECT ON DATABASE MY_DB TO MY_USER;.

Now that you have a clear solution to granting all permissions to a user on a PostgreSQL database, go ahead and try it out!

Let's empower your users to make changes on the DEV environment without risking the integrity of your production objects.
