[Colin Watson <cjwatson@xxxxxxxxxxxxx>]

Colin Watson has proposed merging ~cjwatson/launchpad:db-archive-file-history into launchpad:db-devel.

Commit message:
Add ArchiveFile.date_created and ArchiveFile.date_superseded

LP: #1765933

  Stuart Bishop (stub): db

  Bug #1765933 in Launchpad itself: "Allow building livefses against a view of the archive at a fixed point in time"

This is essentially the same as https://code.launchpad.net/~cjwatson/launchpad/db-archive-file-history/+merge/343750, converted to git and rebased on master, and with a new patch number since we've rebaselined the schema since I originally proposed this.
