Javadoc

Get a Writer instance that encodes directly onto the underlying stream.

The returned Writer should not be closed, as it's a shared object. Writer.flush needs to be called when switching between use of the Writer and use of the PGStream write methods, but it won't actually flush output all the way out -- call #flush to actually ensure all output has been pushed to the server.
