I find that my killed connection server process process disappear in Status
after a long time.

I think pgAdmin sends cancel command through postgres server main process.
So server
receives it immediately and sends it immediately to selected child process.
I don't have an idea what pgadmin cancel command exactly does.
After executing it processes remain visible in Status pane always.
I set log_statement = 'all' in postgres.conf file but cancel command does
not wrote any entry to log file.
There is also Terminate button in Status panel but it is always disabled. I
havent found way to enable it.
