Hi,
- however only superusers can terminate superuser backends.
+ however only superusers can terminate superuser backends. When no
+ <parameter>wait</parameter> and <parameter>timeout</parameter> are
+ provided, only SIGTERM is sent to the backend with the given process
+ ID and <literal>false</literal> is returned immediately. But the
I test the case when no wait and timeout are provided.
True is returned as the following which seems different from the doc.
postgres=# select pg_terminate_backend(pid);
pg_terminate_backend

t
