-- Upgrade the database from commit 3d70a460 to 0983abac.
|
|
--
|
|
-- NOTE: This upgrade must be applied to every schema in the database.
|
|
-- NOTE: Each application starts a transaction, which must be committed
|
|
-- or rolled back.
|
|
--
|
|
-- This:
|
|
--
|
|
-- * makes the primary key on planned_lines deferrable; and
|
|
-- * changes the planned_lines trigger from statement to row.
|
|
--
|
|
-- To apply, run as the dougal user, for every schema in the database:
|
|
--
|
|
-- psql <<EOF
|
|
-- SET search_path TO survey_*,public;
|
|
-- \i $THIS_FILE
|
|
-- COMMIT;
|
|
-- EOF
|
|
--
|
|
-- NOTE: It can be applied multiple times without ill effect.
