Azure Cosmos DB for PostgreSQL | User: postgres | Unable to login To assign Superuser role to another user.

Hello, Welcome to MS Q&A

Microsoft Entra ID integration works with standard PostgreSQL client tools like psql, which aren't Microsoft Entra ID aware and support only specifying the username and password when you're connecting to PostgreSQL. In such cases, the Microsoft Entra ID token is passed as the password.

We tested the following clients:

• psql command line: Use the PGPASSWORD variable to pass the token.
• Other libpq-based clients: Examples include common application frameworks and object-relational mappers (ORMs).
• pgAdmin: Clear Connect now at server creation.

Use the following procedures to authenticate with Microsoft Entra ID as an Azure Cosmos DB for PostgreSQL user. You can follow along in Azure Cloud Shell, on an Azure virtual machine, or on your local machine.

• Use Microsoft Entra ID and native PostgreSQL roles for authentication with Azure Cosmos DB for PostgreSQL

Please let me know if any questions

Kindly accept answer if it helps

@AJITH KUMAR RAI Thank you for reaching out.

This is by design. Some extensions, including pg_vector, require elevated permissions, so can’t be enabled using CREATE EXTENSION command in our managed service.

To enable (and disabled) such extensions you’d need to use create_extension UDF we provide.

For instance,

 SELECT create_extension('vector');

General guidance for this is provided here.
