What is

PostgresDB 38004: Reading SQL Data Not Permitted

 ?
  1. Check the SQL query you are trying to execute to ensure it does not attempt to access restricted data or perform operations outside your permission scope.
  2. Verify the roles and permissions associated with your user account in the PostgreSQL database to ensure you have the necessary access rights to perform the read operation. Use the following SQL command to list your current role and its privileges:
  3. SELECT * FROM information_schema.role_table_grants WHERE grantee = 'your_role_name';
  4. If you have access to modify roles and permissions, and you know the specific table or database you need access to, you can grant select permission to your user role using:
  5. GRANT SELECT ON your_table_name TO your_role_name;
  6. Check the PostgreSQL log files for any additional error messages or details regarding the access denial. This can provide clues on why the access was blocked. The location of the log files can vary, but they are often found in /var/log/postgresql/ on Linux systems.
  7. If your query involves multiple tables or schemas, ensure that the user role has read access to all required tables and schemas.
  8. Confirm that any security policies or row-level security (RLS) policies applied to the tables you are accessing do not restrict your access. You can check for RLS policies with:
  9. SELECT * FROM pg_policies WHERE tablename='your_table_name';
  10. Ensure that your database connection string is correct and that you are connecting to the intended database with the correct credentials.
  11. If you are using a database connection pool or a middleware that manages database connections, ensure that it is configured correctly and that it is not altering your intended SQL queries or database access permissions.
