The cheapest production-HA Postgres — after the disqualifications

Verdict: the cheapest production-HA Postgres on the list can’t legally run the workload. The cheapest one that actually can is PlanetScale — and it sits third on price, not first. Sort by dollars and the answer is a trap.

Why the top of the price list is disqualified

A production-HA workload here demands three things at once: a high-availability standby, point-in-time recovery of a week or more, and HIPAA eligibility. Those are the parity floor — miss one and the price is irrelevant.

The cheapest raw number belongs to DigitalOcean, which undercuts the field by a wide margin — and isn’t HIPAA-eligible, so for regulated production it’s out. The sub-line price buys a database you can’t put the workload on. The catch is that the disqualifications don’t sweep the whole cheap tier: the next two cheapest, PlanetScale and TigerData, both clear the bar. Then Supabase — fourth on price, not last — drops out too, because it ships PITR only as a paid add-on and this workload requires it. So the excluded rows are scattered through the ranking (first and fourth), not stacked at the bottom, which is exactly why taking the cheapest row on faith fails here.

The real floor

Strike the disqualified rows and the cheapest survivor is PlanetScale — a provider you’d never land on by sorting the column, with a struck-out row above it and another just below. It clears HA, PITR, and HIPAA on the priced plan. It also edges out the hyperscalers most teams reach for by reflex, Aurora and Cloud SQL — but only by single-digit percent, not a landslide. The bigger number is what compliance costs you: qualifying at all runs about $164 (roughly two-thirds) more than DigitalOcean’s disqualified sticker price. That gap — not the one to the big clouds — is the price of the workload being allowed to run.

What this means

• Don’t shop this workload on price alone — the cheapest row and the fourth-cheapest each fail a hard requirement, so the ranking actively misleads.
• PlanetScale is the pick for regulated HA: the lowest total that clears every requirement, and a few percent under the Aurora/Cloud SQL reflex.
• The premium here is compliance, not brand. Qualifying costs ~$164 more than DigitalOcean’s disqualified price — far more than the ~$30–40 between PlanetScale and the hyperscalers. The expensive mistake is skipping the capability check, not picking the wrong qualifier.

If your production isn’t actually regulated — no HIPAA, PITR is nice-to-have — then the disqualifications lift and the cheapest raw number is back on the table. The capability floor is only as binding as your compliance requirements; state them first, then read the price.
