 ### PostgreSQL Engine
 
 When you establish an RDS DB cluster or instance using the `postgres`/`aurora-postgresql` DB engine along with a specified `EngineVersion`, LocalStack will dynamically install and configure the corresponding PostgreSQL version as required.
-Presently, you have the option to choose major versions ranging from 11 to 16.
-If you select a major version beyond this range, the system will automatically default to version 15.
+Presently, you have the option to choose major versions ranging from 11 to 17.
+If you select a major version beyond this range, the system will automatically default to version 17.
 
 It's important to note that the selection of minor versions is not available.
 The latest major version will be installed within the Docker environment.
-If you wish to prevent the installation of customized versions, adjusting the `RDS_PG_CUSTOM_VERSIONS` environment variable to `0` will enforce the use of the default PostgreSQL version 15.

 While the [`DescribeDbCluster`](https://docs.aws.amazon.com/AmazonRDS/latest/APIReference/API_DescribeDBClusters.html) and [`DescribeDbInstances`](https://docs.aws.amazon.com/AmazonRDS/latest/APIReference/API_DescribeDBInstances.html) APIs will still reflect the initially defined `engine-version`, the actual installed PostgreSQL engine might differ.
