Overview
The JDBC Driver Class for Redshift Accounts is bundled with the Redshift driver com.amazon.redshift.jdbc42.Driver. This upgrade is backward-compatible; however, the support for the PostgreSQL driver class will end in the November 2023 release. If you are using PostgreSQL driver in your existing accounts, we recommend you to migrate from PostgreSQL driver to 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 be using the Amazon Redshift Driver as default one going forward.
Support for PostgreSQL driver as the default one will continue only up till November 2023. After November we will no longer support PostgreSQL driver as default one.
The existing pipeline still uses postgresql driver as default one till November.
Upgrade:
To upgrade from the PostgreSQL driver to 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.
