Operating system: OSX
Description:

When performing a grant I can do:

GRANT INSERT, UPDATE, DELETE ON TABLE person TO user;

But when creating a policy I can't do:

CREATE POLICY user_write ON person FOR INSERT, UPDATE, DELETE TO user
USING (…);

The specific error is:

ERROR: syntax error at or near ","
LINE 1: ...TE POLICY user_write ON person FOR INSERT, UPDATE, ...

This doesn't seem to be intended as the GRANT specification allows it, and
CREATE POLICY supports the ALL command.
