Thanks for your quick response.

I have copied this configuration file form my installed postgres 8.3.1

I am pasting this file for your reference .
By the way PGDATA is /var/lib/pgsql/data

Yes there is a log file file pgstartup.log
PGLOG=/var/lib/pgsql/pgstartup.log
its contains only ths startup and shutdown messages.

/etc/init.d/postgres file contents
------------------

# PGVERSION is the full package version, e.g., 8.2.0
# Note: the specfile ordinarily updates this during install
#PGVERSION=8.3.1
PGVERSION=8.3.7

PGMAJORVERSION=`echo "$PGVERSION" | sed 's/^\([0-9]*\.[0-9]*\).*$/\1/'`
