Hi, ReorderBufferTupleBuf is defined as follow:
/* an individual tuple, stored in one chunk of memory */
typedef struct ReorderBufferTupleBuf
{
/* position in preallocated list */
slist_node node;
/* tuple header, the interesting bit for users of logical decoding */
HeapTupleData tuple;
/* pre-allocated size of tuple buffer, different from tuple size */
Size alloc_tuple_size;
/* actual tuple data follows */
} ReorderBufferTupleBuf;
However, node and alloc_tuple_size are not used at all. It seems an
oversight in commit a4ccc1cef5a, which introduced the generation
context and used it in logical decoding. I think we can remove them
(only on HEAD). I've attached the patch.
Regards,
