Problem with starting PostgreSQL server 7.4.19

Hello all,
It was running fine initially and the database was lying idle for a
few days. Today I looged into the machine and restarted the server by
killing the process by 'kill -9 pid'. And then restarted it by
'postmaster -i -D /opt/pgsql/data/'.
Then it gives the following error on stdout :

LOG: database system was interrupted at 2008-03-06 14:15:17 IST
LOG: record with incorrect prev-link 1/0 at 0/A4EB08
LOG: invalid primary checkpoint record
LOG: record with incorrect prev-link 42FD/0 at 0/A4EAC8
LOG: invalid secondary checkpoint record
PANIC: could not locate a valid checkpoint record
LOG: startup process (PID 3388) was terminated by signal 6
LOG: aborting startup due to startup process failure

What is the problem? It was running fine all this time.

I have to use an older version for it to be used with another software. So
changing versions is not feasible.

Thanks & Regards,

Kakoli
