Postgres Deletion Strategy Advisor
Build a SaaS tool that inspects schemas, table statistics, and workload patterns to recommend the safest and fastest deletion strategy for each table. It would tell teams when to use batched DELETE, partitioning, copy-and-swap, VACUUM follow-up, or archive-first retention, reducing trial and error and production incidents.
Why this matters
You run a production PostgreSQL system and eventually hit the ugly side of data lifecycle management. Simple-looking delete jobs create bloat, long replication lag, lock contention, or painful vacuum backlog. You know partitions can help, but only for some tables and only if the schema was designed for it. For many workloads, especially transactional ones, the right answer depends on timing, foreign keys, write concurrency, and how much data must be removed. Instead of a clear decision path, you are left with blog posts, hand-built scripts, and risky late-night maintenance windows. What you want is a tool that inspects your database and tells you what to do before you damage performance.

MVP Scope · 1–2 weeks
- Build a connector that pulls table stats, index counts, partition info, and autovacuum settings from PostgreSQL.
- Create a rules engine that classifies tables into time-series, append-heavy, high-churn, or FK-heavy patterns.
- Design a simple web UI for per-table risk summaries and recommended deletion strategies.
- Implement read-only SQL checks for estimated dead tuples, table bloat indicators, and recent write activity.
- Draft 10 recommendation templates covering batch delete, partitioning, truncate, archive-first, and copy-keep-swap scenarios.
- Add pre-flight warnings for exclusive lock risk, foreign key dependencies, and concurrent writer activity.
- Generate downloadable SQL runbooks tailored to each table classification.
- Integrate Slack or email delivery for scheduled reports and risky-operation alerts.
- Add onboarding for managed Postgres connection strings with least-privilege guidance.
- Recruit 5 design partners and validate recommendation usefulness against their past incidents.
Differentiation
Why This Might Fail
Self-rebuttal — the most important trust signal
- 1Teams may trust internal DBA judgment more than a new advisor, especially for production mutations.
- 2The advice may not generalize well across edge cases such as unusual triggers, extensions, or custom replication setups.
- 3Cloud database vendors or open-source extensions may add enough advisory features to compress willingness to pay.
Evidence Summary
How AI synthesized this insight — no verbatim quotes
Discussion participants repeatedly agreed that large deletes create more operational burden than teams expect, and many pointed to partitions, manual vacuuming, or copy-and-swap patterns as workarounds. At the same time, several comments stressed that the right approach depends on concurrency, constraints, workload type, and lock behavior. That combination of recurring pain and decision complexity supports an advisory product.
