Alright, updated patch attached which does just that (thanks to Adam
for the updates for this and testing pg_dump- I just reviewed it and
added some documentation updates and other minor improvements), and
rebased to master. Also removed the catversion bump, so it should apply
cleanly for people, for a while anyway.
This is testing what has been committed:
# create table colours (id serial, name text, visible boolean);
CREATE TABLE
# insert into colours (name, visible) values ('blue',true),('yellow',true),('ultraviolet',false),('green',true),('infrared',false);
INSERT 0 5
# create policy visible_colours on colours for all to joe using (visible = true);
CREATE POLICY
# grant all on colours to public;
GRANT
# grant all on sequence colours_id_seq to public;
GRANT
# alter table colours enable row level security ;
ALTER TABLE
\c - joe
> select * from colours;
id | name | visible
----+--------+---------
1 | blue | t
2 | yellow | t
4 | green | t
(3 rows)

ERROR: new row violates WITH CHECK OPTION for "colours"
DETAIL: Failing row contains (7, transparent, f).

policyname | tablename | roles | cmd | qual | with_check
-----------------+-----------+-------+-----+------------------+------------
visible_colours | colours | {joe} | ALL | (visible = true) |
(1 row)
There was no WITH CHECK OPTION.
