Description: inheritance removes permissions from the parent table
Details:

Hi,
I'm not sure if this is strictly a bug or just a side effect of
inheritance that could do with being added to the documentation.

If you create a new table that inherits from another table - a user cannot
select from the parent if they cannot select from the child.

To recreate:

as dba
create table a (id int);
grant select on a to auser;
insert into a (id) values (1);

as auser
select * from a;
id
----
1

as dba
create table b (data int) inherits (a);

as auser
select * from a;
ERROR: permission denied for relation b

I didn't expect to need permission for table b in order to select from a...
