Well sure you can do that but there isn't anything special about a
delimiter. In general the value is atomic and there isn't anything smaller
than it. You could probably use a CASE expression to append new data to
the value or start the value. It almost sounds like you might want to
check out the array type and work with *that* instead since that at least
is an atomic collection of values. This isn't a case of being destructive,
you just have to include the previous value in the new value you write.
That's just standard stuff.
