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")));
}
