Oh, by the way:

Maybe this isn't clear enough. If you don't know the above tables,
they are system tables (created automatically in every IB/FB database)
and most tools don't show them by default, but you can make them
appear by checking a box that is typically called "Show system info"
or something the like.

You can browse and query them like any other table, but you should
never insert, update or delete something in that region if you don't
know exactly what you're doing.
