RE: Removing the default grant of EXECUTE on functions/procedures to PUBLIC

I apologize, that was sloppy.
I was using the acldefault() function with pg_roles, like this:
=> select rolname, acldefault('f',oid) from pg_roles where rolname like 'mjt%' order by 1;
rolname | acldefault
-----------+--------------------------------------
mjt_test1 | {=X/mjt_test1,mjt_test1=X/mjt_test1}
mjt_test2 | {=X/mjt_test2,mjt_test2=X/mjt_test2}
(2 rows)

I had issued
alter default privileges for role mjt_test1 revoke execute on functions from public;
but had not done a similar ALTER for mjt_test2. And so I was surprised that they both showed a default =X/rolename.

Examining \ddp and its underlying quuery, I see that view column pg_default_acl gets a new row with defaclacl populated after the ALTER DEFAULT PRIVILEGES.

Thanks very much for your guidance, I am on track now.

Er, what? There's no column named acl_default in pg_roles, nor any

other standard PG view.

psql's "\ddp" command is the most usual way to examine current

defaults:

regression=# create user joe;

CREATE ROLE

regression=# ALTER DEFAULT PRIVILEGES FOR USER joe REVOKE EXECUTE ON FUNCTIONS FROM public;

ALTER DEFAULT PRIVILEGES

regression=# \ddp

Default access privileges

Owner | Schema | Type | Access privileges

-------+--------+----------+-------------------

joe | | function | joe=X/joe

(1 row)
