Here is the updated version that contains two patches as described
above.
Here are some minor comments:
o On changes to ExecInsert
* This might be just my taste, but I think it would be better to (1)
change ExecInitPartitionInfo so that it creates and returns a
newly-initialized ResultRelInfo for an initialized partition, and (2)
rewrite this bit:
+ /* Initialize partition info, if not done already. */
+ ExecInitPartitionInfo(mtstate, resultRelInfo, proute, estate,
+ leaf_part_index);
+
/*
* Save the old ResultRelInfo and switch to the one
corresponding to
* the selected partition.
*/
saved_resultRelInfo = resultRelInfo;
resultRelInfo = proute->partitions[leaf_part_index];
+ Assert(resultRelInfo != NULL);
to something like this (I would say the same thing to the copy.c changes):
/*
* Save the old ResultRelInfo and switch to the one corresponding to
* the selected partition.
*/
saved_resultRelInfo = resultRelInfo;
resultRelInfo = proute->partitions[leaf_part_index];
if (resultRelInfo == NULL);
{
/* Initialize partition info. */
resultRelInfo = ExecInitPartitionInfo(mtstate,
saved_resultRelInfo,
proute,
estate,
leaf_part_index);
}
This would make ExecInitPartitionInfo more simple because it can assume
that the given partition has not been initialized yet.
o On changes to execPartition.h
* Please add a brief decsription about partition_oids to the comments
for this struct.
@@ -91,6 +91,7 @@ typedef struct PartitionTupleRouting
{
PartitionDispatch *partition_dispatch_info;
int num_dispatch;
+ Oid *partition_oids;
That's it.
