I have a minor question about the condition:
+ if (pt->commandType == CMD_INSERT ...
Is it possible to get another commandType there?
IIUC, we cant get into
if (defaults_remaining && product_queries != NIL)
only for INSERT ...
In other words, are there other commands that we expect executing
following lines for?
values_rte = rt_fetch(values_rte_index, pt->rtable);
...
rewriteValuesRTEToNulls(pt, values_rte);
(ALSO MERGE is not supported, as I can see)
If the (pt->commandType == CMD_INSERT) check is for safety, maybe it
should be broader?
Thanks for the fix!
(My extra testing discovered no new anomalies in this area.)
Best regards,
Alexander
