PostgreSQL version 11 will reach their official end of life status on the 1st of February 2025. As of this date, these versions will no longer be found in Relational Database Service under PostgreSQL. More information about End of Life for PostgreSQL can be found here.
Existing instances and their functionality or status will remain unchanged, but no new PostgreSQL instances may be created with version 11.
We recommend a "Major Version Upgrade" which was recently published. More information incl. a guide you can find in our Open Telekom Cloud Community Portal.
