Error From Custom Database Profile

 Hi,

I am developing a profile for CockroachDB.  I have a cockroachdb.xml profile that is extending the generic profile.  A have a database profile path configured in preferences.  DbVis sees the profile.

The issue I am having is that I am receiving the following error:

2018-03-30 09:58:08.754 WARN     1 [ExecutorRunner-pool-2-thread-1 - L.ￄﾋ] There is no Command with id suffix: getSchemaNames

I have added a command in the cockroachdb.xml file to override the command in the generic profile:

    <Command id="cockroachdb.getSchemaNames">
      <SQL>
                <![CDATA[
show databases;
         ]]>
      </SQL>
      <Filter index="Database" label="Name"/>
    </Command>

The original error is gone, but now in the Debug Window I get the following error:

 Can you explain what getSchemaNames is used for and what columns it needs?

Thanks
