Postgres will no longer startup

Hi,

I am using an ubuntu 8.10 installation (from linode). I installed postgres
and it was working fine. Then it shutdown and would not start again. When I
tried to start it again I got a perl error saying that the locales where not
set correctly. I fixed that and then it said that no postgres client was
installed so I installed psql. Now when I execute /etc/init.d/postgresql-8.3
start I get no output to the logs or the console, it just returns. I will
post the last sever lines of the log below. Does anybody know what problem
this is and why I started to have it? Thanks,

Josh
