Hi,
What I am concerned about from the report [1] is that this comment is
a bit too terse; it might cause a misunderstanding that extensions can
do different things than we intend to allow:
/*
* 6. Finally, give extensions a chance to manipulate the path list.
*/
if (set_join_pathlist_hook)
set_join_pathlist_hook(root, joinrel, outerrel, innerrel,
jointype, &extra);
So I would like to propose to extend the comment to explain what they
can do, as in the comment about set_rel_pathlist_hook() in allpaths.c.
Attached is a patch for that.
Best regards,
Etsuro Fujita
