Select 256, 512, 1024, 2048 or 4096 MiB RAM; Free permits only 256 MiB. Included total storage is respectively 500, 1024, 2048, 4096 or 8192 MiB, including PostgreSQL and WAL. Seven-day backups are included. Each 256 MiB costs 10 credits per active hour, prorated by time; sleeping costs no active RAM credits. Shared Dev/Prod data changes both environments. A smaller volume requires a separate data migration and is refused here. A brief connection interruption is possible. Poll the original operation until observed completion. The legacy profile input is accepted only for databases still on the transitional provider; it does not imply PGCF autoscaling. ## OpenAPI ````yaml /openapi.json post /v1/projects/{project_id}/database/compute openapi: 3.1.2 info: title: ohmyho.st API version: 0.0.0 description: >- Public REST API for ohmyho.st hosting, projects, domains, email, credits and exports. servers: - url: https://app.ohmyho.st description: Production control API - url: https://dev.app.ohmyho.st description: Development control API security: - BearerAuth: [] paths: /v1/projects/{project_id}/database/compute: post: summary: Select database memory and included storage description: >- Requires project-write access and explicit confirmation.
