I can see how this came about, since the double star in the type is hard to see.
 Too bad we can't fix that.

     while (*schemas) {
-      if (strcmp(schema_name, reinterpret_cast<const char*>(schemas)) == 0)
+      if (strcmp(schema_name, static_cast<const char*>(*schemas)) == 0)
         return true;
       schemas++;
     }
