Thanks for your replying. But actually there are some difference database now, 
and  I really want to define the user-defined function or type one time so that 
 they can be  accessed as system-defined function or type,  how can I do? 
Thanks!

You probably want to use one database with multiple schema instead. See 
the manual for more information about schema.
