Thats not enough information to resolve anything. Please be a bit more
descriptive.

Anyway, its pretty clear that you do not have PGDATA set in the environment..
So you need to run the command as follows:

pg_ctl -D /your/postgres/data/directory start

RTFM will definitely help.

Please DO NOT exclude the list from the conversation. Adding GENERAL again.

I am not able to understand the following line in your error log:
<>
could not change directory to "/root"
</>

maybe someone else can help here.

Are you sure you have a running postgres instance on this box? The 'reload'
command can be executed only for a running Postgres instance.

If postgres is running (ps or top commands can help determine that), then
figure out which directory is that instance using as it's DATA directory. If
postgres is not running, then substitute the 'reload' in your command with
'start'.

If you are still unable to solve the problem, then please send us the output
of following commands: (assuming you are on a nixen (linux/Unix))

ps aux | grep postmaster
ps aux | grep postgres

which pg_ctl


Best regards

Hi again


pg_ctl start is running

pg_ctl start -l logfile -D /var/lib/pgsql/data
could not change directory to "/root"
server starting
************************************************** *******************
Sir there is no any problem if we start rather than reload it.

************************************************** ****************
but if i write
pg_ctl reload -l logfile -D /var/lib/pgsql/data
could not change directory to "/root"
pg_ctl: PID file "/var/lib/pgsql/data/postmaster.pid" does not exist
Is server running?

Here i am writing in /var/lib/pgsql/data
the output of the command which u told me is
