title: Liquibase changesets and PostgreSQL JSONB arrow functions
body: <p>I have a problem with liquibase and PostgreSQL JSONB arrow functions.
  When I trying to use such functions in liquibase changesets, for example:</p>
  
  <p><code>CREATE UNIQUE INDEX foo_index ON public.foo (bar -&gt;&gt; 'bar');</code> </p>
  
  <p>I get some: </p>
  
  <p><code>liquibase.exception.DatabaseException: ERROR: syntax error at or near "-&gt;&gt;"</code></p>
  
  <p>as a result during compilation. Maybe anybody knows how can such behavior be avoided. (Ignore syntax check or rewrite statement maybe).</p>
