How can I troubleshoot the “PostgreSQL role doesn’t exist” issue in SQL?
I was setting up a new user for my PostgreSQL Database. During the process j have created a role and granted the required permissions, however, when I was attempting to log in account using that user, I encountered an error that said “Postgres role does not exist”. What steps should I take to resolve this particular issue?
In the context of SQL if you are facing the error related to “Postgres role does not exist” then it might be due to an attempt to use a role or username that is not created in the database of PostgreSQL. Another possible reason could be that the user doesn’t have the required permissions. The third possible reason could be that the case sensitivity of the role name doesn’t match with the setting of the database.
Here is the sample given how you can troubleshoot and resolve the “postgresSQL role does not exist” error in PostgreSQL:-
Check for typos in the role name or ensure proper case sensitivity
SELECT rolname FROM pg_roles WHERE rolname = ‘your_role_name’;Confirm the user’s existence in the database
du your_role_name
Ensure proper login privileges are granted to the role
GRANT CONNECT ON DATABASE your_database TO your_role_name;Verify the role’s permissions and privileges
dp your_table_name
Check if the role exists in the pg_roles table
SELECT * FROM pg_roles WHERE rolname = ‘your_role_name’;
