One strategy we've considered is to use the same approach as "pstack" on Solaris - it takes a pid and dumps the stack of a backend, which clearly shows which executor node is being worked on currently. I think pstack uses dtrace underneath the hood...
pstack has been around since the SunOS days, long before dtrace was in Solaris, so it at least used to operate some other way. I know they added some features to Solaris 10 that let pstack look into Java librarites that may leverage dtrace, but I don't believe the internals of the main pstack tool rely on it when looking at regular processes.
It's also worth noting that there's a similar Linux utility called gstack. -- * Greg Smith [EMAIL PROTECTED] http://www.gregsmith.com Baltimore, MD ---------------------------(end of broadcast)--------------------------- TIP 4: Have you searched our list archives? http://archives.postgresql.org
