Re: [PATCHES] pg_standby

I confirm that I am seeing the exact same characteristic. Could you post your rotating script?

Thanks,

I double checked and re-ran all my test and confirmed that pg_standby
move (-m) mode is definitely busted in v3 in the sense that a restart
of the standby will not resume recovery and requires a pg_resetxlog to
become operational -- it needs one more WAL file back than  the oldest
one available.

I am currently working around this by rotating WAL files a couple of
versions back in the shell script I am using to receive log files via
netcat.  move mode is very desirable because it keeps the maintenance
down for the standby system.
