Thread: postmaster does not shut down

I can't get pg to shutdown or otherwise respond. I closed the cygwin console window and opened another (PG was working fine with the other window).

$ pg_ctl status
pg_ctl: postmaster is running (pid: 1656)
Command line was:
/usr/bin/postmaster

$ pg_ctl stop -m immediate
kill 1656: No such process
waiting for postmaster to shut down........................
......... failed
pg_ctl: postmaster does not shut down

Hi John,

As a thought, what happens if you try a slightly different syntax of:

$ pg_ctl -m immediate stop

?

Also, does it look like PostgreSQL might be being kept open by a
connection to it from an application or something not closing down?

Regards and best wishes,

I just deleted the pid file and started PG again. I guess closing the window kills it?

Ahhh... you started PostgreSQL from a cygwin window with:

$ pg_ctl start

and then closed the window?  It does seem to like keeping the window
open.  Have you tried starting it using postmaster instead?

$ postmaster -D /path/to/your/data/directory -i

Not sure that will work, but it's a though.

When PostgreSQL is configured to start as a service, it seems to be much
easier.  You can then just start it from the "Services" part of the
Windows control panel (depending which operating system you're using of
course).

Hi all

> I guess closing the window kills it?
No. It doesn't kill postgresql and it doesn't kill the ipc-daemon. If you
look at the win task manager you see the processes still running. You can
kill it with the task manager but this is a rather inelegant way;-)

It works fine;-)
I am starting/stopping the processes with small shell scripts placed in my
home directory. You can see all of them at
http://www.pgsql.info/pg_win.html

To start:
#!/bin/sh
echo
echo "PostgreSQL starten:"
postmaster -i -D /usr/share/postgresql/data &
ps -f

To stop:
#!/bin/sh
echo
echo "PostgreSQL shutdown:"
pg_ctl stop -w -D /usr/share/postgresql/data -s -m smart
ps -f

Same thing happens if I close the window if started with 'postmaster' (btw is there a way to specify the log file this way?).

postmaster shows up in the services, but gives this message when trying to start:

'Could not start the postmaster service on Local Computer. The service did not return an error. This could be an interal Windows error or an internal service error.'
