Обсуждение: failure on 'pg_ctl stop' command

Hi Everybody,

I had a failure on stopping postgres.
The command I issued was:
>> pg_ctl stop -m s

and its response was:
>> waiting for server to shut down............................................................... failed
>> pg_ctl: server does not shut down

I repeated the same command and the response was identical.
I proceeded to issue:
>> pg_ctl stop -m f

and this time it came back with:
>> waiting for server to shut down.... done
>> server stopped

Would somebody please tell me what this means?
Is it indicative of some trouble?  What can/Should
I do to remedy the situation?

My environment is Redhat Linux, Dell AMD 64bit machine
with postgres 8.2.4.

Regards,

Normally this means that you have clients connected to the db while
it's trying to shut down.

On the server, run

ps ax|grep postgres

and look for a client connected in IDLE state.

You can either disconnect all the clients, or use -m f, which will
disconnect them for you.

Many thanks, Scott.
