Hi Masahiko,
I agree. 19 gets a note in the docs, and v6 goes to master first.
The docs patch for 19 is attached. It says what blocks, how to see the
PID, and how to get out. I am happy to change the wording.
For (2), I think it is still worth doing on master even with v6. It
would also cover replay of the enable record and recovery conflicts
with a backend stuck on a client write. Manu, do you want to post it?
If not, I am happy to take it.
Thanks,
Shihao
