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?
It sounds like you want something like Oracle's packages. If so, you're out of luck: postgresql doesn't support anything like that at this point.
Bundle the functions, type definitions, etc up in a .sql file and run that on each database. It's cleanest if you do this by creating a new schema called, say, 'shared', then SET search_path=shared before creating the functions and types. That way they all go in one place that's separated from the per-database content. To access them, SET search_path=shared,public . You can "ALTER USER SET search_path=shared,public" or "ALTER DATABASE SET search_path=shared,public" to make it default.
