Is it possible to operate inside pg_hint_plan function? about pg_hint_plan

[horiguti]

I doubt that EXPLAIN or auto_exaplain shows that but setting pg_hint_plan.debug_print=verbose or details shows the log like the follows if it works correctly.

2020-02-14 13:36:59.956 JST [13475] LOG: pg_hint_plan[qno=0xd]: HintStateDump: {used hints:SeqScan(a)SeqScan(b)}, {not used hints:(none)}, {duplicate hints:(none)}, {error hints:(none)}

But, I should have made a bug here. The hints in the function should apply to the following query but it has no effect at 1.3.4. The same bug is found in back to PG10 and backpatched to the branch.

(That commit for the master branch is the result of wrongly split of the changes. Code change is contained in the previous commit 0576a94 )

Looks like there is nothing left to do here, so closing.
