How do I troubleshoot "permission denied" errors with PostgreSQL ANSI x64 ODBC?

1. Verify the user credentials used in the ODBC connection string are correct. 2. Check the user's privileges using `psql` and the `\du` command to see the roles assigned. 3. Examine the privileges on the specific table/schema using `\dt table_name` or `\dn schema_name`. 4. Use `GRANT` statements in `psql` to grant the user necessary privileges (e.g., `GRANT SELECT ON table_name TO username;`). 5. Ensure the ODBC driver version is compatible with the PostgreSQL server version.
