Where is the qualification par in the Query Tree

This refers to /doc/src/sgml/html/querytree.html, where one mentions a
qualification part in the Query Tree. While reading the Query node
(parsenode.h) and output from the log with debug_print_parse = on, I
cannot see either this part. Is it gone in profit of join tree ?

As noted near the bottom of that documentation page:

It turns out to be convenient to store the top-level WHERE expression
as a qualification attached to the top-level join-tree item, too. So
really the join tree represents both the FROM and WHERE clauses of a
SELECT.

IOW, Query.jointree->quals.
