Apparently I can't do that via Postgres. So I've made a bash script to do the work for me.
The script will only delete the wal_files older than 24h ( -mmin +1440 ) * It has been tested and it's working. *recovery.conf:* > archive_cleanup_command = 'exec nice -n 19 ionice -c 2 -n 7 > ../archivecleaup_mv.bash -d "../wal_archive" "%r"' *archivecleaup_mv.bash:* #!/bin/bash -eu declare -r -x PATH='/usr/local/bin:/usr/bin:/bin'; ARCHIVEDIR='/var/lib/pgsql/9.2/wal_archive/' CHKPOINT=$(find $ARCHIVEDIR -type f -mmin +1440 -name '00*' -printf '%f\n' | sort -r | head -1) #cd $ARCHIVEDIR exec "/usr/pgsql-9.2/bin/pg_archivecleanup" $ARCHIVEDIR $CHKPOINT; find $ARCHIVEDIR -type f -mmin +1440 -a -name '00*' -a ! -newer $CHKPOINT -delete
