BTW, your fix also fixes ALL_FROZEN stuff, just because WAL for heap insert is already emitted by the time of -9.
I want to emphasize that it seems to me that position of injection point is not a hint, but rather coincidental.
I concur that all other users of visibilitymap_clear() likely will need to be fixed. But only when we have a good picture what exactly is broken.
Best regards, Andrey Borodin.
