Win32 doesn't have the granularity to do special signal numbers like we do on Unix, so we have to map control-C to call a special libpq function that communicates with the postmaster/backend to cancel the query. No way an outside process can do that. Your only solution would be to hack psql to accept a signal somehow to call that libpq function, and hack your client to send that signal to psql somehow. -- Bruce Momjian | http://candle.pha.pa.us pgman@candle.pha.pa.us | (610) 359-1001 + If your life is a hard drive, | 13 Roberts Road + Christ can be your backup. | Newtown Square, Pennsylvania 19073 ---------------------------(end of broadcast)--------------------------- TIP 1: subscribe and unsubscribe commands go to [EMAIL PROTECTED]
