Perhaps a bit of background, I started coding Fortran on state of the art 
IBM1620, I whole total 16k of memory.  It filled a large room.  That 
teaches you to conserve assets. I am retired so time is not something I 
worry about.
I wrote my first shopping cart in mid-90's and had a bunch of emails from 
Widenius and  Lerdorf about mysql and php,I was able  break them pretty 
regularly for couple of years.

When I looked at archive table in phpmyadmin it shows index is small.  When 
I look at the actually db files on server --right now each day archive used 
almost 100k, so removing say 25 columns is a bunch and also makes 
everything run faster.   

Anyway still don't understand why I would get errors if weewx truely just 
looks at the column list.

This is a lot better than sitting in  front of a tv eating chips.
