Hi Henson,

> Attached is the v47 patches for Row pattern recognition (SQL/RPR).

While looking into v47, I noticed that
raw_expression_tree_walker_impl() lacks tracking RPCommonSyntax and
its children nodes. Probably this does nothing wrong with RPR
functionalities but just for completeness I created a patch on top of
v47.
