Hi Jasen. Storing the record in text format will difficult furter
analisis (p.e.searching columns with differences between OLD and NEW).
It will not be easy to play with NEW as string for obtaining each column
values (string_to_array will not work, the values for NEW can be anything)
As this trigger will save information for audit, it is important to get
it right.
Even worst, im *strongly encouraged* not to use any other language
except plpgsql, so i cant use plpythonu, in wich will be trivial to do so.
thanks for your time, Jasen
