Issues with privileges carrying over after alter table owner

we have added some default users to the template1 db so we can grant ro and rw privs as needed per owner.

For example

If I create table "yyy" as a special user with a set of privileges, the grantee and gantor data from thopse privs are there.

jorge_dev=# select * from information_schema.table_privileges where table_name = 'yyy';

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

(12 rows)

jorge_dev=#

If I create table 'xxx' as a different user, then alter the table owner the grantor and grantee information is not carried over.

For example, this is a table created under a different user than altered to owner migration

jorge_dev=# select * from information_schema.table_privileges where table_name = 'xxx';

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

(7 rows)

How can we get all the privileges and grants inherited when a table owner is altered ?

Thanks,

Jorge Torralba

That is not the behavior I see:

create table ownertest(id int);
alter table ownertest owner to joe;
grant select on table ownertest to alice;
select * from information_schema.table_privileges where table_name =
'ownertest';
 grantor | grantee | table_catalog | table_schema | table_name |
privilege_type | is_grantable | with_hierarchy
---------+---------+---------------+--------------+------------+----------------+--------------+----------------
 joe     | joe     | deepdive      | public       | ownertest  | INSERT
        | YES          | NO
 joe     | joe     | deepdive      | public       | ownertest  | SELECT
        | YES          | YES
 joe     | joe     | deepdive      | public       | ownertest  | UPDATE
        | YES          | NO
 joe     | joe     | deepdive      | public       | ownertest  | DELETE
        | YES          | NO
 joe     | joe     | deepdive      | public       | ownertest  |
TRUNCATE       | YES          | NO
 joe     | joe     | deepdive      | public       | ownertest  |
REFERENCES     | YES          | NO
 joe     | joe     | deepdive      | public       | ownertest  | TRIGGER
       | YES          | NO
 joe     | alice   | deepdive      | public       | ownertest  | SELECT
        | NO           | YES
(8 rows)

alter table ownertest owner to mary;
select * from information_schema.table_privileges where table_name =
'ownertest';
 grantor | grantee | table_catalog | table_schema | table_name |
privilege_type | is_grantable | with_hierarchy
---------+---------+---------------+--------------+------------+----------------+--------------+----------------
 mary    | mary    | deepdive      | public       | ownertest  | INSERT
        | YES          | NO
 mary    | mary    | deepdive      | public       | ownertest  | SELECT
        | YES          | YES
 mary    | mary    | deepdive      | public       | ownertest  | UPDATE
        | YES          | NO
 mary    | mary    | deepdive      | public       | ownertest  | DELETE
        | YES          | NO
 mary    | mary    | deepdive      | public       | ownertest  |
TRUNCATE       | YES          | NO
 mary    | mary    | deepdive      | public       | ownertest  |
REFERENCES     | YES          | NO
 mary    | mary    | deepdive      | public       | ownertest  | TRIGGER
       | YES          | NO
 mary    | alice   | deepdive      | public       | ownertest  | SELECT
        | NO           | YES

You will need to tell us exactly what version of postgres you are
running and show us precisely what commands are being run (as I have
above - a self contained test case) if you want us to be able to help.
