Postgres database problem

You really, really, really need to update to some remotely-modern PG
version. 7.0 *will* eat your data someday.

NOTICE: mdopen: couldn't open /var/lib/pgsql/data/pg_log: Permission denied

So, what's the permissions on /var/lib/pgsql/data/pg_log ?
(Hint: should be mode 600 owner postgres)

psql: pqReadData() -- backend closed the channel unexpectedly.
This probably means the backend terminated abnormally
before or while processing the request.

(2) When i am trying to connect via application it is giving error

[root@imap GroupSMS]# java SendGrpSmpp

Hola , probá
chown -r postgres: /var/lib/pgsql/data

el "-r" es para que sea recursivo
