turning of pg_xlog

Hi,

I have installes Postgres 8.0.15 on a embedded Linux and have only 130
MB for Postgres.
Is it possible to turn off the comlete (Wal) pg_xlog? Because this is
the biggest part.
I found an Entry how to minimize the count of stored xlogs.
Is it possible to store it  to /dev/null or something else?
Something like ln -s /dev/null  pg_xlog/ (I know this does not work :-) ....
