Are you sure about that? What version are you running? I get
play=> select version();
version
------------------------------------------------------------------
PostgreSQL 7.0.2 on hppa2.0-hp-hpux10.20, compiled by gcc 2.95.2
(1 row)
play=> select usename, usesuper from pg_user;
usename | usesuper

postgres | t
tgl | f
tree | f

play=> select current_user;

play=> create table bar (f1 int);

play=> select * from bar;

play=> grant all on bar to tree;
CHANGE
play=> select * from bar;
ERROR: bar: Permission denied.
play=> grant all on bar to tgl;

play=> select * from bar;

play=>
AFAICT from both experiment and looking at the sources, a table
owner is allowed to change the table's access permissions whether
or not he's currently got any permissions granted to himself;
ie, changing permissions is not a grantable/revokable right,
it's just checked on the basis of who you are.
