Greetings.
1) What is the table 'dellog' for?
2) Why 'comments' table does not have a foreign key on 'docs'?

It's a leftover from the old search engine iirc. I assume there's noting
interesting in it? If not, it can go.

Oversight I guess. Feel free to add one.

Yep, the table is empty.

There are some problems with this... Run the following query
SELECT id, version, file
FROM comments c
WHERE NOT EXISTS (
SELECT id
FROM docs d
WHERE d.version = c.version AND
d.file = c.file
);
and observe the comments that are linked to non-existant pages of
documentation. Someone'll have to fix these before adding a foreign key
will be possible.
