How to remove user specific grant and revoke

[Andrus <kobruleht2@xxxxxx>]

User groups table is defined as

    CREATE TABLE IF NOT EXISTS public.kaspriv
    (
        id serial primary key,
        user character(10) NOT NULL,
        group character(35) NOT NULL
    ...
    )

There are hundreds of users. Earlier time grant and revoke commands were executed for every user separately. Later revoke and grant commands for public were added:

    REVOKE ALL ON TABLE public.kaspriv FROM PUBLIC;
    GRANT SELECT ON TABLE public.kaspriv TO PUBLIC;

pgAdmin SQL tab still shows revoke and grant commands for every user also:

    REVOKE ALL ON TABLE public.kaspriv FROM PUBLIC;
    REVOKE ALL ON TABLE public.kaspriv FROM someuser;
    REVOKE ALL ON TABLE public.kaspriv FROM someotheruser;
    ...
    GRANT SELECT ON TABLE public.kaspriv TO PUBLIC;
    GRANT SELECT ON TABLE public.kaspriv TO someuser;
    GRANT SELECT ON TABLE public.kaspriv TO someother;
    ...

How to remove those unnecessary user-specific GRANT and REVOKE commands to make rights cleaner? pgAdmin does not have delete option for those.

Something like

    DROP REVOKE ALL ON TABLE public.kaspriv FROM all EXCEPT public;
    DROP GRANT SELECT ON TABLE public.kaspriv FROM all EXCEPT public;

This will be one-time action. It can be done manually in pgadmin or using some script running once.

Using

    PostgreSQL 12.2 (Debian 12.2-2.pgdg100+1) on x86_64-pc-linux-gnu,
    compiled by gcc (Debian 8.3.0-6) 8.3.0, 64-bit

and latest pgAdmin 7.2
