Hello,

In PostgreSQL, when you create a function, you may choose between SECURITY
INVOKER or SECURITY DEFINER:
http://www.postgresql.org/docs/8.2/static/sql-createfunction.html
When a function has SECURITY INVOKER (the default), the SQL it contains is
run with the permissions of the invoking user.

It seems that DB2 UDFs uses SECURITY DEFINER (using PostgreSQL terms), and
that there is no way to change that. Or? Is there a way for me to provide
a UDF to a lot of users but prevent the contained SQL from being executed
with my permissions?
