Cannot Drop Role with "Replication" Attribute in Azure PostgreSQL Flexible Server 16

Question

Hello,

I am encountering the following error when trying to drop a role that has the "REPLICATION" attribute enabled.

ERROR: permission denied to drop role
Detail: Only roles with the CREATEROLE attribute and the ADMIN option on role "test_replication" may drop this role.
SQL Error [42501]: ERROR: permission denied to drop role
Detail: Only roles with the CREATEROLE attribute and the ADMIN option on role "test_replication" may drop this role.

Some context:

Environment: Azure Database for PostgreSQL Flexible Server (version 16.8)

Authentication: PostgreSQL authentication only

This "admin" user created the role test_replication but is unable to drop it.

To investigate, we ran the following script:

DROP ROLE IF EXISTS test_noreplication;  

CREATE ROLE test_noreplication WITH  
LOGIN  
NOSUPERUSER  
INHERIT  
CREATEDB  
NOCREATEROLE  
NOREPLICATION;  

DROP ROLE IF EXISTS test_replication;  

CREATE ROLE test_replication WITH  
LOGIN  
NOSUPERUSER  
INHERIT  
CREATEDB  
NOCREATEROLE  
REPLICATION;  

After running the script, we confirmed that we cannot drop the role that has the REPLICATION attribute enabled.

Thanks! Looking forward to your insights.
