Example session with this skill installed
Need a safe plan to add a unique lower-case email column to our 5M row users table without locking production. Give me the steps and the SQL for Postgres.
- Read your context and instructions
- Compiled the migration-safety-pro
Strategy: Expand-Contract (Zero-Downtime)
- Add 'email_lower' as nullable VARCHAR.
- Code Change: Dual-write to both 'email' and 'email_lower'.
- Batch Update:
UPDATE users SET email_lower = LOWER(email) WHERE id IN (...)
LIMIT 500;
- Finalize: Set NOT NULL and add UNIQUE INDEX CONCURRENTLY.
