Description:

Hi,

Testing with version 

<dependency>
            <groupId>org.postgresql</groupId>
            <artifactId>postgresql</artifactId>
            <version>42.2.5</version>
        </dependency>


I am using postgres with hibernate and during the close() call from the Jdbc
template is called, the connectionClosed() from the event listner is not
being called. i see the listener is being invoked from
fireConnectionClosed() but this should also be invoked from close() method.
