when ordering the input rows for a “normal” aggregate for which ordering is optional. There is a subclass of aggregate functions called ordered-set aggregates for which an order_by_clause is required, usually two characters indicate the general class of the condition, the last three characters indicate a subclass of the general condition. A successful state is indicated by the code 00000. The SQLSTATE codes them to abort and raise an exception. Both plpy.execute and plpy.prepare can raise an instance of a subclass of 5. http://docs.python.org/library/stdtypes.html#iterator-types 6. http://www.python.org/dev/peps/pep-0249/
