If I unstand you correctly, I have to write a function in my PostgreSQL 
database. I never programmed a function in PostgreSQL by my 
self...should this be sth. like a Trigger: so the Trigger startet after 
the user created the object?! and wrote the message? and stop the action 
saving the new point in my database!

Has anybody else an idea?
