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.
