Given the following snippet:
HeapTupleHeader tuple;Datum temp;bool isnull;tuple = PG_GETARG_HEAPTUPLEHEADER(0);temp
=GetAttributeByName(tuple, "data", &isnull);
When using this for a btree operator functions, you need to
PG_FREE_IF_COPY(?,?);
Which of the above parameters need I free?
tuple, or temp,.... Or both?
