Hi Team,

I came across an issue while working with acldefault function on materialized view, which threw an error "ERROR: unrecognized objtype abbreviation: m", when I looked at the source code of acldefault_sql it seems that materialized view case is not handled there, the SQL statement which I was executing is as follows,

`select relname, relowner, acldefault(relkind, relowner) as acl from pg_class where relkind in ('r', 'p', 'v', 'm');`


Please note that the value of relacl column in pg_class is NULL, upon assigning the permission explicitly the error goes away.

I'm not sure if it is truly a bug or I have some misunderstanding about the function.

Your guidance will be helpful to get better understanding of the issue.

Thank you.

No, acldefault doesn't consider 'm' to be valid input, because
materialized views are not a distinct kind of object for ACL purposes;
they're just relations (tables), and have relation-y privileges.

In fact, none of the object type codes accepted by acldefault_sql
are relkind values, except for the accidental overlap of 'r' with
the relkind for plain tables.
