- * TupleTableSlot information

- * shouldFree boolean - should we call pfree() on tuple
- * descIsNew boolean - true when tupleDescriptor changes
- * tupleDescriptor type information kept regarding the tuple data
- * buffer the buffer for tuples pointing to disk pages
- *
- * The executor stores pointers to tuples in a ``tuple table''
- * which is composed of TupleTableSlot's. Some of the tuples
- * are pointers to buffer pages and others are pointers to
- * palloc'ed memory and the shouldFree variable tells us when
- * we may call pfree() on a tuple. -cim 9/23/90

- * In the implementation of nested-dot queries such as
- * "retrieve (EMP.hobbies.all)", a single scan may return tuples
- * of many types, so now we return pointers to tuple descriptors
- * along with tuples returned via the tuple table. -cim 1/18/90
