Re: odd buildfarm failure - "pg_ctl: control file appears to be corrupt"

I'm planning to push 0002 (retries in frontend programs, which is
where this thread began) and 0004 (add missing locks to SQL
functions), including back-patches as far as 12, in a day or so.

I'll abandon the others for now, since we're now thinking bigger[1]
for backups, side stepping the problem.
