title: Hibernate tools schemaexport without destroying current data
body: <p>I'm doing an <code>org.hibernate.tool.hbm2dll.SchemaExportTask</code> as part of my compile/build script (it is ant with hibernate4 plugin, if it is important).</p>
  
  <p>Everything works wonderfully, except one:</p>
  
  <p>It destroys all data!</p>
  
  <p>What I want, is realistically a simple database dump, an equivalent of "<code>pg_dump --all</code>" or like. It doesn't matter, if it is based on the xml configuration, or on the current database.</p>
  
  <p>I don't want any modification on the real db, and particularly don' want any actually executed drop/create operations.</p>
  
  <p>Is it possible anyhow in the sphere of the hibernate tools jars?</p>
