Yeah, you are right but in the original code it's:

values = (Datum *) palloc(natts * sizeof(Datum));
nulls = (bool *) palloc(natts * sizeof(bool));

I just typed it wrong, I didn't copy and paste. I also forgot to add this line (from valgrind log) at the beginning of
errorsequence: 

==30549== Warning: set address range perms: large range 496753892 (undefined)

I'm clueless, any hints?
