I've granted privileges, but I'm still getting ODBC error 13. What else could be the problem?

1. Ensure you've granted privileges to the correct database user. 2. Double-check the spelling of the table and schema names in your SQL query and `GRANT` statements. 3. Consider if the user is connecting through a role. Privileges might need to be granted to the role, and the user granted membership to the role. Use `GRANT role_name TO username;`. 4. Restart the PostgreSQL service after making significant privilege changes to ensure they take effect immediately.
