Actually, the one time I've written an application with select * in it
was when I wrote some simple, generic app that used select * to root out
the layout of the table and make a simple edit screen for any generic
table in postgresql. It used select * from table limit 1 to get the
layout, and using libpq was able to find the type of each field and
thereby produce a proper update / insert query.

But any REAL application should never do that, I agree.
