# PostgreSQL TimescaleDB versions and configurations

PostgreSQL versions 14, 15, 16, and 17 are supported. A specific version of TimescaleDB is installed for each PostgreSQL version. You can [find out the TimescaleDB version](#find-out-timescaledb-version) after [creating a cluster](/managed-databases/timescaledb/create-cluster.mdx).
