Summarizing:
so we want some kind of super postmaster that starts some processes
(including the postgres' postmaster itself), and track their
availability.
- processes that doesn't need to connect to shared memory should start
here (ie: pgagent, slony daemons, pgbouncer, LISTEN applications, etc)
- processes that need to connect to shared memory should be childs of
postgres' postmaster
is this so different from what the postgres' postmaster itself does? i
mean, can we reuse that code?
this project of course growth beyond my known abilities, so while i
will try it (if anyone seems like he can takle it please go for it)...
maybe we can add this to the TODO if seems acceptable? specially, i'd
love to hear Tom's opinion on this one...
