-my first suggestion may have been hare-brained, but why not just make the
-specifics of the output user-configurable. So if the user chooses \0, so
-be it, if the user chooses \N so be it, if the user likes NULL so be it.
-but the option would only have one value per database at any given point
-in time. so database x could use \N on tuesday and NULL on wednesday, but
-database x could never have two references to the characters(s) used to
-represent a null value.

-Watching all this go by...as a guy who has to move alot of data
-from legacy dbs to postgres, I've gotten used to \N being a null.
-
-My vote, if I were allowed to cast one, would be to have one null
-and that would be the COPY command null. I have no difficulty
-distinguishing a null from a newline...
-
-At the pgsql command prompt I would find seeing \N rather reassuring.
-I've seen alot of these little guys.
