    PostgresProvider: Do not set GErrors without a domain.
    
    * providers/postgres/gda-postgres-provider.c:
      gda_postgres_provider_create_operation(),
      gda_postgres_provider_render_operation(),
      gda_postgres_provider_perform_operation():
      Use GErorr domain=GDA_SERVER_PROVIDER_ERROR and
      code=GDA_SERVER_PROVIDER_OPERATION_ERROR instead of 0, 0 for
      generic errors, because that is what users of GdaServerProvider
      expect.
