I guess I was thinking about this:
http://groups.google.com/groups?selm=10897.953919427%40sss.pgh.pa.us
"Average width is pretty bogus because the thing really doesn't haveany idea of the average length of variable-length
columns. I'm thinkingabout improving that in the future, but it may not be worth the trouble,because the width isn't
usedfor very much."
I also think that it is used that much: if you look at all the EXPLAINS
that have come across the various lists over the years, very few (if any)
utilize the "width" in any important way. It's important for computing
the cost, but I would like to suggest that the extra "noise" should be
off by default as most people never make use of it, and an EXPLAIN ANALYZE
is already quite verbose.
