-- Fix final_lines_summary view
--
-- New schema version: 0.6.1
--
-- ATTENTION:
--
-- ENSURE YOU HAVE BACKED UP THE DATABASE BEFORE RUNNING THIS SCRIPT.
--
--
-- NOTE: This upgrade only affects the `public` schema.
-- NOTE: Each application starts a transaction, which must be committed
-- or rolled back.
--
-- This update adds a default user to the system (see #176, #177, #180).
-- The default user can only be invoked by connecting from localhost.
--
-- This user has full access to every project via the organisations
-- permissions wildcard: `{"*": {read: true, write: true, edit: true}}`
-- and can be used to bootstrap the system by creating other users
-- and assigning organisational permissions.
--
-- To apply, run as the dougal user:
--
-- psql <<EOF
-- \i $THIS_FILE
-- COMMIT;
-- EOF
--
-- NOTE: It can be applied multiple times without ill effect.
