Hi Tomas,
I will let you know about check_postgres.pl.
We will explore pgmonitor as well.
The other tool we are working on is pgwatch, we found this very useful.
Thanks

Looks like this is generally an area that can be targeted by some
businesses. Or an open source enthusiast.
One centre that captures all the information and produces a report
based on it would be a great thing. Especially in cases like mine,
where I have tens of postgresql installations on
Since you are using except and not except all, you are not looking at
arrays with duplicates.
For this case next function what the fastest for me:
create or replace function array_except2(anyarray,anyarray) returns
anyarray as $$

Here's a case which it seems like we ought to be able to optimize for:

Is there some non-obvious reason which would make this kind of

Tom,
In principle, yeah, we could make it do that, but it seems like a likely
source of maintenance headaches. This example is not exactly compelling
enough to make me want to do it. Large OFFSETs are always going to be
problematic from a performance standpoint, and the fact that we could

It has a hot table analysis report that shows the number of scans, rows
