Here is what I found with the new code. Seems it works.

---------------------------------------------------------------------------

test=> create table test (x char(8104));
CREATE
test=> insert into test values ('x');
INSERT 21417 1
test=> insert into test values ('x');
INSERT 21418 1
test=> insert into test values ('x');
INSERT 21419 1
test=> insert into test values ('x');
INSERT 21420 1
test=> vacuum;
VACUUM
test=> delete from test;
DELETE 4
test=> vacuum;
VACUUM
