Hmm, I think we have small issue if the last WAL segment restored from
the archive is an incomplete one:
All normal archive recoveries have "complete" WAL files, since an xlog
switch record jumps past missing entries at the end of the file. So I
was just about to say "how can it be an incomplete one?", to which the
answer is file damage of some kind causing a failed CRC check.
So yes, it is possible and no, the patch doesn't work that way yet.
Actually, the code already deals with that possibility. That's the
motivation for the timelines: the new WAL record will be generated with
a new timelineid. We never append to an existing WAL file after archive
recovery.
Now I'm confused. You're disagreeing with what you just said?
Right. I thought I found a problem, but then I found out that it's not a
problem. Aka false alarm.
