Обсуждение: User with GRANTS only on Views. Lock table on function will work?

Hi,

I have a database were the users only can do operations using views, they have not access to physical tables. But I have a function with a lock on a physical table. Can I allow this users to run a function that locks a physical table?

Best Regards,

You can create a function with SECURITY DEFINER, allowing it to be run
with the privileges of the users who created it rather than the user who
is running it. See here:

  http://www.postgresql.org/docs/8.4/static/sql-createfunction.html

Would this do what you need?
