Overview
From the March 2023 (4.32.1.0) release, the JDBC driver class for Redshift Accounts will use the Redshift driver com.amazon.redshift.jdbc42.Driver as the default driver. This upgrade is backward-compatible; however, the support for the PostgreSQL driver class will end by the November 2023 release. Therefore, we recommend you to migrate from the PostgreSQL driver to the Redshift driver, if you are using the PostgreSQL driver in your existing accounts.
Things to remember:
Amazon Redshift Driver will be the default driver from the March 2023 (4.32.1.0) release. The new pipelines will use the Amazon Redshift Driver as the default driver from the March 2023 release.
Support for the PostgreSQL driver as the default driver will continue until November 2023. So your existing Pipelines can use the PostgreSQL driver as the default one until November 2023. If you continue to use the PostgreSQL driver beyond November 2023, your Pipelines will break.
Upgrade:
To upgrade from the PostgreSQL driver to the Redshift driver as the default driver, you must update the Driver class name in the Account settings from “org.postgresql.Driver” to "com.amazon.redshift.jdbc42.Driver" in your existing accounts.
