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. If you are using the PostgreSQL driver in your existing accounts, we recommend you to migrate from the PostgreSQL driver to the Redshift driver.
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 one from the March 2023 release.
Support for PostgreSQL driver as the default will continue until November 2023. After November, we will no longer support the PostgreSQL driver as the default one.
The existing pipelines can use PostgreSQL driver as default one till November.
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.
