Heikki,
I ran into an unexpected issue while testing. I just wanted to fire up
a chain of 5 replicas to see if I could connect them in a loop.
However, I ran into a weird issue when starting up "r3": it refused to
come out of "the database is starting up" mode until I did a write on
the master. Then it came up fine.
master-->r1-->r2-->r3-->r4
I tried doing the full replication sequence (basebackup, startup, test)
with it twice and got the exact same results each time.
This is very strange because I did not encounter the same issues with r2
or r4. Nor have I seen this before in my tests.
Ok.. I'm going to need some more details on how to reproduce this, I'm
not seeing that when I set up four standbys.
Ok, I managed to reproduce this now.
Hmph, no I didn't, I replied to wrong email. The problem I managed to
reproduce was the one where you get "requested WAL
segment 000000020000000000000003 has already been removed" errors,
reported by Thom.
