Moving pg_xlog problem

Hi,

I am trying to move the pg_xlog directory to another disk by using a
symbolic link. But I keep getting the following error message:

Panoramix:/var/lib/postgresql/8.0/main# /etc/init.d/postgresql-8.0 start
Starting PostgreSQL 8.0 database server: main(FAILED)

The PostgreSQL server failed to start. Please check the log output:
LOG: could not load root certificate file
"/var/lib/postgresql/8.0/main/root.crt": No SSL error reported
DETAIL: Will not verify client certificates.
LOG: database system was shut down at 2005-11-08 08:01:12 CET
PANIC: could not open file
"/var/lib/postgresql/8.0/main/pg_xlog/00000001.history": Permission
denied
LOG: startup process (PID 14242) was terminated by signal 6
LOG: aborting startup due to startup process failure

I followed this procedure:

As root:
/etc/init.d/postgresql-8.0 stop

As postgres
cd /var/lib/postgres/8.0/main
mv pg_xlog/ pg_xlog_orig
mkdir /opt/postgres/logs/wal
ln -s /opt/postgres/logs/wal pg_xlog
cp -r pg_xlog_orig/ pg_xlog

As root:
/etc/init.d/postgresql-8.0 start

What did I do wrong, and even more important, what should I do?

TIA
