Best way is to NOT grant multiple users permissions, but to grant a
role the permissions and grant that role to users. That way you only
have to revoke persmissions from the role to revoke it from all the
users.

Note that you can build a set of revoke commands by using selects and
concatenations if you need them. Something like this (use psql -E to
see the queries \ commands invoke in psql)
SELECT 'revoke all from somename on '||n.nspname||'.'|| c.relname ||';'
FROM pg_catalog.pg_class c
JOIN pg_catalog.pg_roles r ON r.oid = c.relowner
LEFT JOIN pg_catalog.pg_namespace n ON n.oid = c.relnamespace
WHERE c.relkind IN ('r','v','S','')
AND n.nspname <> 'pg_catalog'
AND n.nspname !~ '^pg_toast'
AND pg_catalog.pg_table_is_visible(c.oid)
ORDER BY 1;
?column?

revoke all from somename on public.colony;
revoke all from somename on public.delegate;
revoke all from somename on public.jt1;
revoke all from somename on public.jt2;
revoke all from somename on public.mytable;
revoke all from somename on public.test1;
revoke all from somename on public.test2;
revoke all from somename on public.tmp;
