                 The error message will consist of a Tcl command name and a colon
                 (":"), an error string, and a trailing &lt;newline&gt; character.  If
                 the database was opened in an environment, the Tcl command name will
                 be the environment name (for example, env0), otherwise it will be the
                 database command name (for example, db0).
