Frequently Asked Questions
What is STACKIT PostgreSQL Flex?
STACKIT PostgreSQL Flex is a fully managed database-as-a-service for PostgreSQL. It offers flexible resource scaling for CPU, RAM, and storage through various predefined configurations (flavors).
Which PostgreSQL versions are supported?
STACKIT supports several current PostgreSQL major versions in parallel, currently including PostgreSQL 14, 15, and 16. Older versions reach end of support on a fixed schedule (version 14, for example, at the end of 2026), so timely upgrades are recommended.
Which extensions are available?
STACKIT PostgreSQL Flex supports a broad range of common PostgreSQL extensions. The database owner has the permissions needed to enable supported extensions independently.
How does high availability work?
In replica-set mode, STACKIT runs multiple replicas of the database, increasing availability compared to a single instance. Failover behavior details are documented in the current STACKIT documentation.
Is point-in-time recovery possible?
Yes, STACKIT creates continuous backups and allows restoration within the configured backup period. An instance-specific daily backup time can be defined.
