Thanks. I have been looking at the _cluster.sl_status table, and it's
been really useful. The only problem I've got now is I would like to be
able to do some calculations with the st_lag_time field in
_my_cluster.sl_status table. As it is stored as an Interval, I would
really like it in just one format (e.g. seconds) so I could use it as an
integer. At the moment it looks something like this...

ipt=# select st_lag_time from _my_cluster.sl_status;
st_lag_time
-----------------
00:00:02.114107
(1 row)

I have looked into converting Interval Types, but have been told that
this conversion will no longer be supported by Postgres.

Any ideas?

Regards,

Aaron
