ERROR: could not create unique index "ht_user_pkey"

There is a unique index on user_id in the 8..4.0 system and, of
course, only one record for 653009.
Are you sure there is just one record? I had this same problem and it
was because there were a few rows that violated the primary key even
though the constraint existed since table creation. The db had a hard
crash once which might explain the bad data though.
run this to check your whole table for duplicates:
select user_id, count(*)
from ht_user
group by user_id
having count(*) > 1;
-nigel.
