PostgreSQL

With IONOS CLOUD Database as a Service, you can set up and manage a PostgreSQL database. Leverage our user guides, reference documentation, and FAQ to support your hosting needs.

Important:

• Effective September 15, 2026, PostgreSQL v1 functionality will be fully deactivated in both the DCD and API. Use PostgreSQL v2 to create and manage clusters using the DCD or the API.
• Cluster creation using PostgreSQL v1 API is deprecated since July 15, 2026. In the DCD, only limited operations are supported on legacy (existing v1) clusters.
• Existing PostgreSQL v1 clusters will be automatically migrated to the new PostgreSQL v2 infrastructure starting July 29, 2026. No user action is required and we will notify you before the migration. If you prefer to migrate earlier, see Manual migration.
