CREATE EXTENSION IF NOT EXISTS pgaadauth;

ERROR: extension "pgaadauth" is not allow-listed for "azure_pg_admin" users in Azure Database for PostgreSQL

HINT: to learn how to allow an extension or see the list of allowed extensions, please refer to https://go.microsoft.com/fwlink/?linkid=2281561

ALTER SYSTEM SET cron.database_name = 'postgres';

SELECT pg_reload_conf();

ERROR: permission denied to set parameter "cron.database_name"

Hi @Aditya Singh,

Welcome to the Microsoft Q&A Platform! Thank you for asking your question here.

We would like to inform you that, The error message indicates that the pgaadauth extension is not allow-listed for azure_pg_admin users. In Azure Database for PostgreSQL - Flexible Server, azure_pg_admin does not have superuser privileges, meaning some extensions and system configurations require Microsoft’s approval.

Azure requires allow-listing for extensions like pgaadauth. To check the allowed extensions, execute the below mentioned sql query. If pgaadauth is missing, you must explicitly request Microsoft to allow it. Raise a support ticket through Azure Portal.

SELECT * FROM pg_available_extensions;

Once approved, You can run:

CREATE EXTENSION pgaadauth;

If it remains blocked, you cannot manually install it without Microsoft’s intervention.

To add the pg_cron extension and configure it for your database, follow these steps:

Enable the Extension: First, you need to enable the pg_cron extension by modifying the server parameters.

Go to your PostgreSQL server in the Azure portal.

Click on the "Server parameters" blade.

Search for the shared_preload_libraries parameter and add pg_cron to it.

Configure pg_cron: After enabling the extension, you can configure it to schedule jobs in your database.

From a PostgreSQL client, log in to the server.

Issue the following command to check if pg_cron is enabled:

SHOW shared_preload_libraries;

You should see pg_cron in the output

Set cron.database_name Parameter: To set the cron.database_name parameter, you need to have the appropriate permissions. Unfortunately, only the azure_superuser role has the necessary permissions to set this parameter and reload the configuration.If you encounter permission issues, you might need to contact Azure support for assistance.

Schedule Jobs: Once pg_cron is enabled and configured, you can schedule jobs using the extension. For example, to schedule a job that runs every day at 10:00 AM, you can use the following command:

SELECT cron.schedule('0 10 * * *', 'VACUUM');

This command schedules a VACUUM operation to run daily at 10:00 AM
