When encountering the error "2F003: Prohibited SQL Statement Attempted" from a Postgres database, and assuming there is no database administrator to assist, follow these immediate actions:
- Identify the SQL Statement: Determine the exact SQL statement causing the error. If it’s from an application, check the application logs to find the statement. If you are running queries manually, note the last query attempted.
- Review PostgreSQL Logs: Check the PostgreSQL logs for more details on the error. Use the command:
tail -n 100 /var/log/postgresql/postgresql-<version>-main.log
- Replace
<version> with your PostgreSQL version. This command shows the last 100 lines of the log, which should include details on the prohibited statement. - Check User Permissions: Ensure the user executing the statement has the necessary permissions. You can check your current role's permissions with:
SELECT * FROM pg_roles WHERE rolname = current_user;
- Examine Active Roles and Their Permissions: If the issue might be permission-related, verify the roles and their permissions using:
\du
- This command lists all roles and their attributes.
- Review Database Security Policies: If your database uses Row-Level Security (RLS) or other security policies that might block certain statements, review these policies. Check for RLS with:
SELECT * FROM pg_policies;
- And for other policies or restrictions, consult the specific configurations or extensions you've used.
- Attempt Statement with Superuser Role (Caution Advised): If possible and appropriate (with caution and understanding the risks), try executing the statement as a superuser. This can help determine if the problem is permission-based. Switch to the superuser (usually
postgres) and try the statement again. However, this step should be taken with full awareness of the potential for causing unintended changes or security implications.
Remember: Directly modifying database roles, permissions, or security settings should be done with a clear understanding of the implications and preferably not under normal user operations without DBA guidance.
