Currently, I am manually matching these two sets of pages by matching titles.
That is how you have to do it. Finding a title with the same name but
in the associated talk namespace. Core namespace are given a number
between 0 and 99, by convention odd ones are the talk pages.
I have two questions:
1) If this foreignkey does not exist, would it be worthwhile to create it?
I do not think we want to add database constraints. It is probably a
good thing but I am almost sure it will break the software in a lot of
different and "interesting" ways.
2) If this foreignkey does exist, what would it take
to expose this in
the XML dumps?
Maybe we can change the XML format. Adding a new field indicating there
is a talk page for the given page should be trivial.
