Re: restore_command ignored in recovery.conf on standby

[Rene Romero Benavides <rene.romero.b@xxxxxxxxx>]

What I did (I bet there's a better way) is this:
restore_command='/db/standby_node/scripts/wal_restore.sh %f %p'

# wal_restore.sh
#!/bin/bash
/bin/tar -xzf /db/wal_archives/$1.tar.gz -C /tmp
cp /tmp/$1 $2
rm /tmp/$1

My best regards to Stephen Frost.

Err, sure, but that isn't actually what is being passed via %p.  %p will
be something like 'pg_xlog/RECOVERY_WAL', as I said, which *won't* work
for your tar command, eg:

sfrost@tamriel:/home/sfrost> tar -xzf zz.tar.gz -C zz/zz
tar: zz/zz: Cannot open: No such file or directory
tar: Error is not recoverable: exiting now
sfrost@tamriel:/home/sfrost> echo $?

Noooo, PG tells you via %p the *specific* filename to use, do not just
overwrite files in pg_xlog willy-nilly with a tar command.
