Embedded postgresql server languages come in two versions, trusted and 
untrusted.  The "java" language is trusted meaning that it won't let 
normal users escape security permissions setup for them.  For example if 
they could open any file, they could open the database files directly and 
read data they shouldn't have access to.  You probably want the "javaU" 
language which is untrusted.
