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.
