Hi!
I have a table where I repeatingly log the status of some service, which
looks something like this:
< timestamp, status >
Now, everytime my service is up I save the timestamp and a status of
"up", if it's down I save the timestamp with "down", eg:
10:13 up
10:14 u
Thanks all. I will try some of these suggestions.

1. will there be any gaps in between dates? if yes, what should be diff
be then?
2. can't you calculate it in client application?
3. is usage of pl/pgsql acceptable (i think this will be the fastest way
to do it in

Hi All,
I have a view that generates output similar to this.
select * from foo.view;
ts | size
---+-
2002-03-16| 11
2002-03-17| 16
2002-03-18| 18
2002-03-19| 12
I am trying to find the difference between the size column. So
11 matches
