Обсуждение: ctrl+C

Hi,

After I do psql, if I hit ctrl+C, it will terminate postmaster.
The message in the log is :

DEBUG:  fast shutdown request
DEBUG:  aborting any active transactions
FATAL 1:  This connection has been terminated by the administrator.
DEBUG:  shutting down
DEBUG:  database system is shut down


I wonder how to disable ctrl+c shutting down db.
thanks,
kathy

That is not what I get in psql. Are you sure that is what you mean. Perhaps you
mean you have started the postmaster and in the same terminal issued the
ctrl-c?

Can you give more details? PostgreSQL version, OS, the commands issued spring
to mind as being useful to know.

It sounds like you've launched the postmaster from the same shell you
are running psql in, and the shell thinks that the postmaster is still
part of the process group it should kill on control-C.

You didn't say what OS this is, but you probably need one or both of:

* launch the postmaster from a different shell process (making a script
to launch it will fix this);

* make sure postmaster's stdin, stdout, stderr are all redirected away
from the terminal.

On some OSs redirecting does not automatically detach from the control
terminal.
