Re: Raw parse tree is not dumped to log

> Updated the patch to v3 version.

I have looked into this patch.

diff --git a/doc/src/sgml/config.sgml b/doc/src/sgml/config.sgml
index 20ccb2d6b54..4370e8307f2 100644
--- a/doc/src/sgml/config.sgml
+++ b/doc/src/sgml/config.sgml

Around line 7407 of config.sgml:

        These parameters enable various debugging output to be emitted.
        When set, they print the resulting parse tree, the query rewriter
        output, or the execution plan for each executed query.

I think you should add "the resulting raw parse tree" before "the
resulting parse tree" since the paragraph refers to the each item in
the varlistentry above.

I'm tempted to change "if (Debug_print_raw_parse)" to:

    if (unlikely(Debug_print_raw_parse))

But as we have similar if-statements elsewhere
(e.g. Debug_print_parse), maybe we should keep it for a separate
commit.
