Some questions:
1. I think, hooks ExplainOneQuery_hook_type, explain_per_plan_hook_type,
explain_per_node_hook_type deserve to be moved to explain_format.h
At least, inside the hook, we usually use functions like ExplainProperty.
-1, because the hooks will be called from explain.c, not explain_state.c.
Ok.
2. In my patch I inserted the hook before the line 1894:
/* in text format, the first line ends here */
Why have you chosen a different way? I don't have specific reasons to
insist, except the extension data right under the node looks better to
me personally.
Tom discusses why we shouldn't try to add to the first line in
http://postgr.es/m/2234935.1741809...@sss.pgh.pa.us and I'm fully in
agreement.
I agree with him, too. But, as you can see, I proposed not changing the
first string or adding something there but just putting extension data
under that line. Extra information about workers' state (not so
important most of the time, I should say) sometimes makes it difficult
to read.
I've committed 0001 and 0002 for now. The additional hook for
cross-option validation can be added in a separate commit. v6-0003,
now v7-0001, needs more substantive review before commit. I hope it
gets some, and soon.
Ok, I am ready to review it thoroughly, if needed.
