    Metadata details:
    filename: postgres_schemadump.rb
    path of file: ./repos/metasploit-framework/modules/auxiliary/scanner/postgres
    
    the code of the file until where you have to start completion: ##

    database_names = session ? [session.client.params['database']] : smart_query('SELECT datname FROM pg_database').to_a.flatten
    if database_names.empty?
      print_status("#{rhost}:#{rport} - No databases found")
      return pg_schema
