|

|

-- Date: 2026-02-XX

-- This migration reverses the changes made in 000014_add_group_name.up.sql
|
||
|
|

||
|
|
-- Step 1: Drop materialized view
|
||
|
|
DROP MATERIALIZED VIEW IF EXISTS user_group_suggestions_mv;

|
|
-- Step 2: Drop indexes on group_name

|
DROP INDEX IF EXISTS idx_tasks_group_name;

||

|
DROP INDEX IF EXISTS idx_wishlist_items_group_name;

|
||
|
|

-- Step 4: Add back project_id to wishlist_items

-- Step 5: Try to restore project_id from group_name (if possible)
|
||

|
-- Note: This is best-effort, as group_name might not match project names exactly
