Re: Grant execute on functions; related objects permissions ?

In PostgreSQL 7.3 you have option to execute function with owner's rights or caller's rights. Default is caller's rights (as it was before 7.3), you probably want owner's rights. See development version of docs:

http://developer.postgresql.org/docs/postgres/sql-createfunction.html

btw, views "execute" also with owner's rights, ie if you grant select on view, you do not have to grant select on every table used in view. Still current_user in view returns "caller", while maybe it should return owner?
