I don't think the behavior you described would be correct. But works
for me on 8.3.18 (see testcase below), and I don't see any bugfixes
like this in the 8.3.x release notes. Are you able to produce a
self-contained test case?

-- These commands were run as user 'josh'
test=# CREATE TABLE fred (wilma text);
CREATE TABLE
test=# GRANT INSERT, DELETE, UPDATE ON fred TO dummy;
GRANT
test=# \z fred
           Access privileges for database "test"
 Schema | Name | Type  |         Access privileges
--------+------+-------+-----------------------------------
 public | fred | table | {josh=arwdxt/josh,dummy=awd/josh}
(1 row)

test=# ALTER TABLE fred ALTER COLUMN wilma SET DEFAULT 'dino';
ALTER TABLE
test=# \z fred
           Access privileges for database "test"
