PostgreSQL mapping doesn't display the related objects

When you configure multiple objects as the source type in a mapping and select objects that have a primary key and foreign key relationship using the Add Related Objects option, the related objects are not displayed.

This issue occurs when you connect to a PostgreSQL database version 15.x or 16.x using the PostgreSQL connection and the JDBC driver from either the base or rollback folder.

To fix this issue, configure the JDBC driver from the latest folder for the PostgreSQL connection.

For more information about configuring the latest JDBC driver, see Configure the JDBC driver for PostgreSQL Connector Knowledge article.
