Hi list!

We have a daemon programme that acts as a pgsql client. It writes in a
DB the status of its own clients. And we have a different daemon that
needs to read that status information and decide upon it. The problem
is that the first daemon is a little fragile and from time to time it
crashes. I need to be able to monitor its connection to the PgSQL and
if it drops (times-out) to mark the status of all of its clients as
"unavailable" or "unknown".

At first I thought about attaching a trigger to pg_stat_activity
table, so on delete I could take action. The only problem was it is
not a table.

Any ideas?
