The code I showed in my last mail was actually test code only. The logic
is more complicated, and I'm not sure it's possible to implement it with
a SELECT... CASE. What's more, the "get_lines" function already exists,
and is already used in different parts of the database. I would like, if
possible, to use it without changing it, or duplicating code.
