You may want to be careful about what signal you submit.
If you do "kill -9", for instance, that may be a more severe
"thwacking" of the system than you intended.
Hitting it with "kill -2" is usually the right answer; that's SIGINT.
Other signals may cause the database to kill ALL the backends.
"kill -3", for instance...
"kill -9" will terminate the whole database system, 'with extreme
prejudice,' which will be quite likely to turn out badly :-(.
