+-- Make feeds.user_id NOT NULL

+-- SQLite does not support ALTER COLUMN directly, so we need to:
+--  1. Temporarily disable foreign key constraints
+--  2. Create a new table with the correct schema
+--  3. Copy data from the old table
+--  4. Drop the old table
+--  5. Rename the new table
+--  6. Re-enable foreign key constraints
+
+-- Disable foreign key constraints temporarily
+PRAGMA foreign_keys=OFF;
