Re: simple division

Use CAST() instead of ::.

SELECT CAST(alldefects AS NUMEREIC(10,4))/wordcount;

I didn't formulate my question properly, because the query went like

of putting the double colon seemed to work.

The Postgres notation of this simple procedure is very unintuitive. I haven't 
been able to remember several times, and most people think of me as a person 
with a reasonably good memory. There is no obvious place in the documentation 
to look this up.

Your answer is 2.0 instead of the correct 2.5 - you need to cast

     before the division, not after.
