Обсуждение: Warm standby terminate itself?

Hi,
I set up an warm standby server which fetches WAL logs from a remote
server. It has been working very well. But today, I was editing the
restore script(which is set as the restore_command) with vi. Just right
after I saved the script, I noticed suddenly the standby server
terminated. I checked log and only found these:

scp: /dbbk/postgres/logarch/0000000100000079000000B3.gz: No such file or
directory #this is in my script and it unzip the WAL log if it exists
2011-09-20 23:56:50 CST FATAL:  could not restore file
"0000000100000079000000B3" from archive: return code 65280
2011-09-20 23:56:51 CST LOG:  startup process (PID 2153) exited with
exit code 1
2011-09-20 23:56:51 CST LOG:  terminating any other active server processes

I believe the script doesn't exit with 0 for any error(and it has been
working smoothly without any modification after server restart). After I
started the server, it just restored passing the file without problem
and it can live with file "No such file" warning because the master
server hasn't generated the log yet. I have no idea why the restore
failed. But even the restore fails, why it lead to a server crash(looks
like so)?

Updating a recovery script while it is executing is a problem.  I
tend to update a copy of the script, stop the warm standby, mv the
copy into place, and start the warm standby.  You can do that
without kicking it out of recovery status.

Got it. thanks.
