/Var Partition Full - How can a change PGDATA? - Mailing list pgsql-novice

Hi

I´m in a big trouble. I need a help!!

My /var server partition  is full. I copied data dir to another partition. I changed owners of dirs and files (postgres.postgres) . I changed /etc/init.d/postgresql PGDATA to a new value, but when I try to load postgresql,this message appears

---pgstartup.log
runuser: warning: cannot change directory to /var/lib/pgsql: No such file or directory
runuser: warning: cannot change directory to /var/lib/pgsql: No such file or directory
----

I have a PostgreSQl 8.2.6 on a RHE4 Server
All my systems are stopped. Please a need some help.
There is no enough free space at /var . I cleaned all log files, but without success 

Thanks
