-- Upgrade the database from commit 78adb2be to 7917eeeb.
--
-- This upgrade affects the `public` schema only.
--
-- It creates a new table, `info`, for storing arbitrary JSON
-- data not belonging to a specific project. Currently used
-- for the equipment list, it could also serve to store user
-- details, configuration settings, system state, etc.
--
-- To apply, run as the dougal user:
--
-- psql < $THIS_FILE
--
-- NOTE: It will fail harmlessly if applied twice.

    key text NOT NULL primary key,
