-- will automatically add unique IDs to Jobsets.
ALTER TABLE Jobsets
  ADD COLUMN id SERIAL NOT NULL,
  ADD CONSTRAINT Jobsets_id_unique UNIQUE (id);
Jobsets: add a SERIAL, unique, non-null id column A postgresql column which is non-null and unique is treated with the same optimisations as a primary key, so we have no need to try and recreate the `id` as the primary key. No read paths are impacted by this change, and the database will automatically create an ID for each insert. Thus, no code needs to change. 2020-02-05 19:06:21 +00:00			`-- will automatically add unique IDs to Jobsets.`
