Re: restore_command ignored in recovery.conf on standby

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.
