Postgres Migration Review: Locks + Rollback Plan
Postgres Migration Review: Locks + Rollback Plan
One purchase gives you a reusable local review Skill for every PostgreSQL migration PR, not a single report.
Paste migration SQL, an ORM migration, a PR diff, or an ordered release set. Get a complete pre-merge artifact with exact lock risks, safer DDL, rollout and rollback boundaries, monitoring SQL, and a paste-ready PR comment.
What you get
- PASS, REVISE, or BLOCK verdict
- statement-level lock, table-rewrite, data-loss, index, constraint, and backfill findings
- safer PostgreSQL DDL alternatives with the evidence still required
- expand, backfill, validate, switch, and contract deployment sequence
- rollback boundaries and application-compatibility checks
- lock timeout, statement timeout, test, and monitoring plan
- paste-ready pull-request review comment
- a short "what would change the verdict" section for every REVISE or BLOCK result
Free checker vs full review
| Free Migration Checker | Full Migration Review |
|---|---|
| GREEN, AMBER, or RED screen | PASS, REVISE, or BLOCK engineering verdict |
| risky-pattern flags | statement-level lock and rewrite reasoning |
| missing production facts | safer DDL and exact evidence required |
| merge-gate handoff | rollout, rollback, monitoring, tests, and PR comment |
Three review modes
- Quick PR: one SQL snippet or ORM migration
- Release Gate: ordered migration set plus application deployment sequence
- Zero-Downtime: expand-and-contract design for a risky schema change
Best input
Provide the SQL or migration files, PostgreSQL version, table size or row count, write rate, transaction behavior, deployment order, rollback window, and existing indexes. Missing production facts are called out rather than guessed.
Example input
ALTER TABLE orders ADD COLUMN status text NOT NULL DEFAULT 'pending';
CREATE INDEX idx_orders_customer_id ON orders(customer_id);
The review identifies unknown production facts, separates the column rollout from the backfill and enforcement steps, evaluates index lock behavior, and adds rollback and monitoring checks.
Start in 3 steps
- Download and unzip once.
- Add the folder to a compatible AI client.
- Reuse it for each SQL snippet, ORM migration, PR diff, or release folder.
One-time Download for US$19. No additional API key. No database connection. It never executes migrations. Production safety still depends on the real PostgreSQL version, table size, traffic, transaction behavior, deployment tooling, backups, and human approval.
