It could be done, but would be extremely slow and awkward using current PL/
pgsql syntax.    You'd have to query the system tables for a list of columns, 
and then execute a series of dynamic queries.

I recommend instead one of the following two approaches:

1) Simply log the whole row of each archived table and don't worry about 
logging the individual columns, or

2) Use PL/tcl, PL/Pyton, or C where you can select columnns by ordinal 
position or other dynamic factor.
