Hi,
I am kinda puzzled as to why the query_tree_walker() function does not
examine the intoClause field? I do see another function
raw_expression_tree_walker() which does walk that entry. So what is
the exact reason here? Or we just missed it for the earlier function?
Regards,
Nikhils

Self answer: Because the post-analysis phase does not have anything
interesting to peek in it. The only interesting thing could be the
RangeVar, but it is not going to be in an RTE form after the
transformstmt, so not much point.
Sorry for the noise.
Regards,
Nikhils
