The same idea that you referred to as pg_system occurred to me, too. But I wondered if the archiver process can get the pid of its child (shell? archive_command?), while keeping the capabilities of system() (= the shell). Even if we fork() and then system(), doesn't the OS send SIGQUIT to any descendents of the archiver when postmaster sends SIGQUIT to the child process group? > # Is there any means to view the whole of a thread from archive? > # I'm a kind of reluctant to wander among messages like a rat in > # a maze:p You can see the whole thread by clicking the "Whole Thread" link.
