pg_dump is not a SQL command implemented by the DB backend. It is an
executable client program that connects to the DB backend itself and
runs various SQL queries to extract the database structure and data.
If you want to run pg_dump from Java, you need to be using
Runtime.exec() or similar.
You could also reimplement pg_dump's logic using JDBC, but I strongly
recommend you don't do that!
