Hi,

If a backend killed by pg_terminate_backend(), the backend returns
57P01 which is identical to the one when it's killed by postmaster.

Problem is, pgpool-II needs to trigger failover if postmaster goes
down because apparently pgpool-II cannot use the PostgreSQL server
anymore.

On the otherhand, pg_terminate_backend() just terminates a backend. So
triggering failover is overkill.

Maybe we could make PostgreSQL a little bit smarter so that it returns
a different code than 57P01 when killed by pg_terminate_backend().

Comments?
