You're right. 'cp <nonexistent> <somewhere>' exits with the status
code 1 (or 256?).
The quoted log lines simply show that segment for tli=3 did not exist
and that for tli=2 had been gotten finally. It's quite normal and
irrelevant to the trouble mentioned. Sorry for the confusion.
Unfortunately, the script attached didn't reproduce the situation for
me. But in the log attached,
> [Standby] 2013-04-22 01:27:25 EDTFATAL: XX000: could not receive data from WAL stream: FATAL: requested WAL segment
000000030000000000000014has already been removed
> cp: cannot stat `../arc/000000030000000000000014': No such file or directory.
> [Standby] 2013-04-22 01:27:30 EDTDEBUG: 00000: unexpected pageaddr 0/6000000 in log file 0, segment 20, offset 0
seems showing that the standby received negative ack for the request
for 20th segment, and 5 seconds later, it tried to get that from
archive and somehow thought that it'd gotten but the header is of 6th
segment.
