Hi there, I'm a newbie to postgresql and I have some problems working with its permissions. For security purpose, I want that my application service account only has execution permissions to the functions I created. so what I did is: Create a group testgroup (not super user) Create a user testuser belongs to testgroup Now I want to give function execute permission to testgroup: first I grant the schema: GRANT USAGE ON SCHEMA "aaa" TO "testgroup"; second I grant the execution permission to the group: GRANT EXECUTE ON FUNCTION "aaa"."testFunction"(integer) TO "testgroup"; I thought that's it and logged in with testuser. But I found I couldn't execute the function and gave me error like: ERROR: permission denied for relation Tablename (the function select from that Tablename) Then I tried to give that testuser the select permission to that Tablename, testuser can then execute that function. so conclusion: it seems it's useless to give execution permission to a group. The group will have to have all the base table select/insert/ delete etc permisisons in order to execute function depending on what's in the function. Then I wonder why Postgresql is working like that? There's no way for me to lock down all base table access. Or is there something I miss? Please help me if you have any idea about locking down base table access and only give function execution access to a group.
