How to manage WAL

Hi all

I would like to known what's best way to manage the WAL.

Let's me explain :

    at beginning I do something like

        psql -c "select pg_start_backup('complete');"
        rsync /pgsql backup_server:
        psql -c "select pg_stop_backup();"

and I backup /WAL directory but after sometime the /WAL directory
become big. So can I do something like

    postgresql stop
    rm /WAL/*
    postgresql start
    psql -c "select pg_start_backup('complete');"
    rsync /pgsql backup_server:
    psql -c "select pg_stop_backup();"

and continu to backup /WAL ?

Regards.
