Re: [HACKERS] make async slave to wait for lsn to be replayed

Hello,

BTW I noticed that 
https://coverage.postgresql.org/src/backend/commands/waitlsn.c.gcov.html
says that lsn_cmp is not covered by the tests.  This probably indicates
that the tests are a little too light, but I'm not sure how much extra
effort we want to spend.

I'm still concerned that WaitLSNCleanup is only called in ProcKill.
Does this mean that if a process throws an error while waiting, it'll
not get cleaned up until it exits?  Maybe this is not a big deal, but it
seems odd.
