On Unix-oid systems, we expect the kernel to restrict who can do a kill() on a postgres process. If there's any similar restriction on who can send to that named pipe in the Windows version, it's not obvious from the code. Do we have/need any restriction there? regards, tom lane -- Sent via pgsql-hackers mailing list (email@example.com) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
