I have a database server with multiple databases (~5) and some
persistent connections using the pgtcl interface.
If I want to shutdown the database server (smart mode) my persistant
connections prevent the postmaster from shuting down (as documented),
if I user fast mode, the shutdown get's done, but without any
notification to the clients. An error is only triggered, if I issue
sql commands, but unfortunately some applications send commands at a
very low rate, but i'd like to get the shutdown information
immediatly.
using LISTEN gives me an error message immediately when issuing the
shutdown
> FATAL 1: This connection has been terminated by the administrator.
>no connection to the server
obviously there seems to be some notification, but I do not know it's
name :-(
I thought of sending notifications by hand before invoking "pg_ctl
stop -m fast" but I don't want to reinvent the wheel.
Is there a notification sen't out in either smart or fast shutdown
mode ?
