PostgreSQL versions 9.5, 9.6 and version 10 will reach their official end of life status on the 1st September 2024. As of this date, these versions will no longer be found in Relational Database Service under PostgreSQL.
Existing instances and their functionality or status will remain unchanged, but no new PostgreSQL instances may be created with version 9.5, 9.6 and version 10.
We recommend a "Major Version Upgrade" which was recently published. More informationen incl. a guide you can find in our Open Telekom Cloud Community Portal.
