Обсуждение: Canceling other backend's query

Hi,

Can i cancel querys runing on other backends, or disconnect a client
from the server? I can kill the backend process, but sometimes this
causing shared memory troubles.

If you kill -9 a backend, you will cause the shared memory problem.  Try 
just a plain kill <pid>.  That should work without causing shared memory 
to dump.

See the 'postgres' manual page for a list of signals and their effects.
