Where this provider fails

3 open clusters

Database branch creation fails silently if region not pre-warmed

high

Calling `POST /api/v2/projects/{project_id}/branches` against a region with no warmed compute returns success but the branch is unusable for ~90s. Agents writing migrations against the new branch hit connection refused.

POST /api/v2/projects/{project_id}/branches

Test-mode credentials require separate billing flow

high

To get sandbox API keys, the agent must complete card verification on a separate dashboard URL. Blocks fully automated agent onboarding.

account setup
26events·stable·last seen1w ago·priority76

Connection string returned without pooler suffix by default

medium

Provisioned connection strings omit `?sslmode=require&pgbouncer=true`. Agents using ORMs with default pools hit “too many connections” within a few hundred rows.

GET /api/v2/projects/{id}/connection_uri
