I don't think it is a good idea. Since you are worried about this, I am going
to guess that the users are running a client (such as psql) to do their
inserts and deletes. If so, they are going to be able to find out the
table names. If this isn't the case and everything is being done by
an application running on the server, then you should be having that
application control access.

You will break things if you prevent people from reading the system catalogs.
