Does this means that the two features are independent one from each other ?
In other words, can we say that JDBC batch will limit information
exchange between client and server while Postgres prepared statements
will optimize their execution ?

The JDBC driver's batch processing is more efficient than regular
execution because it requires fewer network roundtrips so there's less
waiting. The JDBC batch is broken into an internal batch size of 256
statement and all of these are sent over to the server at once.
