I find that my killed connection server process process disappear in Status after a long time. > If pgAdmin's cancel is just dropping the connection, the server might > take some time to notice it, especially if it's in the process of running > a query and doesn't have reason to talk to pgAdmin. 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.
