Обсуждение: information_schema.role_table_grants differs from relacl

Hello,

there seems to be a difference between information_schema and pg_catalog when it comes to privileges.

pg_class and pgAdmin III show ACL = arwdDxt

pgAdmin III displays this as:
GRANT ALL ON TABLE blabla.tabelle TO benutzer;

However, information_schema.role_table_grants has is_grantable = YES for every privilege_type on this view for the user
inquestion. 

The user is owner of the view and also superuser.

So my question is: is is_grantable not the same as 'WITH GRANT OPTION'?

Could you tell me, please?

Thank you very much,

Peter

An object's owner always has all grant options.  By convention, this
isn't explicitly represented in the acl array; rather it's hard-wired
into the backend code behavior.  There is some info about how to read
acl values in the Notes section of the GRANT reference page.
