Hi Man,

I checked the comment:

* inFromCl marks those range variables that are listed in the FROM clause.
* It's false for RTEs that are added to a query behind the scenes, such
* as the NEW and OLD variables for a rule, or the subqueries of a UNION.

Even the RTEs are not directly listed in FROM, but as we are rewriting the
match pattern using join and where clause, I tend to agree with the fix.

 Would you consider adding this to the commitfest?

Best regards,
Henson
