Update counter when row SELECT'd ... ? - Mailing list pgsql-sql

I have a simple table:

name, url, counter

I want to be able to do:

SELECT * FROM table ORDER BY counter limit 5;

But, I want counter to be incremented by 1 *if* the row is included in 
that 5 ... so that those 5 basically move to the bottom of the list, and 
the next 5 come up ...

I've checked CREATE TRIGGER, and that doesn't work 'ON SELECT' ... is 
there anything that I *can* do, other then fire back an UPDATE based on 
the records I've received?

Thanks ...
