What happens then? Looks like a recursion to me? You invoke a TCE main 
hook ony any DB operation and so any call to your hook triggers another.

What do you want to do? It's not clear to me when you want to create the 
extra page record. Whenever an admin adds a certain record? Maybe you 
want to check at least the $table argument in the hook. Otherwise any 
INSERT/UPDATE will result in a new page.
