Nope, sorry, COPY lacks the "READ MY MIND" option. If the incoming
data doesn't include every column of the table, you have to specify
a column list to tell it which columns the data does include.
Possibly you could make your code robust against table alterations by
having it look into the system catalogs to get the current column
list. Then it could leave out the column name(s) it knows a-priori
aren't in the data.
