The TOC doesn't need to be "flowable" in the way that text in a
paragraph is - we can assume that the text of a contents entry and the
associate page number will fit happily on one line, so that's OK. But
it will be multi-page, and I won't know how many pages until I've read
through the database once; I could do that for an optimisation, I
suppose, and then only need to go back and fill in the page numbers. So
that's fine.

Ideally, I want each page to have a centred footer with the text "Page X
of Y" where Y is the total number of pages; obviously that will need to
be filled in retroactively too. So it looks like two passes: one to
produce the numberless table of contents and the actual body of the
document, and one to go back and fill in page numbers in the TOC and on
every footer.

Sounds doable, I think, based on what you've said. Excellent! Goodbye,
Rasmus, hello Guido!
