--- First restore the old columns:
-ALTER TABLE threads ADD COLUMN author_name VARCHAR;
-ALTER TABLE threads ADD COLUMN author_email VARCHAR;
-ALTER TABLE posts ADD COLUMN author_name VARCHAR;
-ALTER TABLE posts ADD COLUMN author_email VARCHAR;
-
--- Then select the data back into them:
-UPDATE threads SET author_name = users.name,
-                   author_email = users.email
-  FROM users
-  WHERE threads.user_id = users.id;
-
-UPDATE posts SET author_name = users.name,
-                 author_email = users.email
-  FROM users
-  WHERE posts.user_id = users.id;
-
--- add the constraints back:
-ALTER TABLE threads ALTER COLUMN author_name SET NOT NULL;
-ALTER TABLE threads ALTER COLUMN author_email SET NOT NULL;
-ALTER TABLE posts ALTER COLUMN author_name SET NOT NULL;
-ALTER TABLE posts ALTER COLUMN author_email SET NOT NULL;
-
--- reset the index view:
-CREATE OR REPLACE VIEW thread_index AS
-  SELECT t.id AS thread_id,
-         t.title AS title,
-         t.author_name AS thread_author,
-         t.posted AS created,
-         t.sticky AS sticky,
-         p.id AS post_id,
-         p.author_name AS post_author,
-         p.posted AS posted
-    FROM threads t
-    JOIN (SELECT DISTINCT ON (thread_id)
-           id, thread_id, author_name, posted
-          FROM posts
-          ORDER BY thread_id, id DESC) AS p
-    ON t.id = p.thread_id
-    ORDER BY t.sticky DESC, p.id DESC;
-
--- reset the search view:
-DROP MATERIALIZED VIEW search_index;
-CREATE MATERIALIZED VIEW search_index AS
-  SELECT p.id AS post_id,
-         p.author_name AS author,
-         t.id AS thread_id,
-         t.title AS title,
-         p.body AS body,
-         setweight(to_tsvector('english', t.title), 'B') ||
-         setweight(to_tsvector('english', p.body), 'A') ||
-         setweight(to_tsvector('simple', t.author_name), 'C') ||
-         setweight(to_tsvector('simple', p.author_name), 'C') AS document
-    FROM posts p
-    JOIN threads t
-    ON t.id = p.thread_id;
-
-CREATE INDEX idx_fts_search ON search_index USING gin(document);
-
--- and drop the users table and columns:
-ALTER TABLE posts DROP COLUMN user_id;
-ALTER TABLE threads DROP COLUMN user_id;
-DROP TABLE users;
