As far as I remember, we hold a cleanup lock on posting tree root.
We cannot process interrupts while holding a LWLock.
I'm afraid to fix this problem we need a real page deletion with
full fledged concurrency protocol as we do it in B-tree or GiST.
I've written a patch for this in 2018. I hope to return to this one day.
Best regards, Andrey Borodin.
