Re: PL/Python array support

CREATE OR REPLACE FUNCTION incr(stuff int[]) RETURNS int[] AS $$
for x in stuff:
     yield x+1
$$
LANGUAGE 'plpythonu';

# select incr(ARRAY[1,2,3]);
ERROR:  invalid memory alloc request size 18446744073709551608
CONTEXT:  while creating return value
PL/Python function "incr"


Suppose, it could be fixed by additional check in PLy_function_handler near line 
947 :
if (proc->is_setof) {
  ...
}
else if (PyIter_Check(plrv))
{
     ereport(ERROR,
            (errcode(ERRCODE_DATATYPE_MISMATCH),
             errmsg("returned object should be iterated"),
             errdetail("PL/Python returns iterable object in non-setof returning 
context")));
}
