Psycopg2.errors.insufficientprivilege: permission denied for schema public

psycopg2.errors.insufficientprivilege: permission denied for schema public

Error: You are encountering the “psycopg2.errors.insufficientprivilege: permission denied for schema public” error.

Description: This error occurs when the current database user does not have sufficient privileges to access the specified schema “public” in the PostgreSQL database.

Solution: To resolve this error, you need to grant the necessary privileges to the user. You can do this by following these steps:

  1. Connect to a user with sufficient privileges, such as the database superuser (e.g., “postgres”).
  2. Execute the following SQL command to grant the necessary privileges to the user experiencing the error: 
    GRANT USAGE ON SCHEMA public TO [username];

    Replace [username] with the name of the user experiencing the error.

  3. If the user should also have privileges to perform other actions on the schema (e.g., creating tables), you can grant additional privileges using the following commands: 
    GRANT SELECT, INSERT, UPDATE, DELETE ON ALL TABLES IN SCHEMA public TO [username];
GRANT EXECUTE ON ALL FUNCTIONS IN SCHEMA public TO [username];

    Again, replace [username] with the name of the user experiencing the error.

Here’s an example of granting necessary privileges to the user “myuser” in PostgreSQL:

GRANT USAGE ON SCHEMA public TO myuser;
GRANT SELECT, INSERT, UPDATE, DELETE ON ALL TABLES IN SCHEMA public TO myuser;
GRANT EXECUTE ON ALL FUNCTIONS IN SCHEMA public TO myuser;

After granting the necessary privileges, the user should now be able to access and perform actions on the “public” schema without encountering the “psycopg2.errors.insufficientprivilege: permission denied for schema public” error.
