The query used indexscan. I tried using trim in userid and I got something
like ...
migrate=# select userid from users where trim(userid) = 'reynan(at)yahoo(dot)com';
userid
---------------------
reynan(at)yahoo(dot)com
(1 row)

I thought it was a varchar problem ('coz userid is varchar) of 7.0.3 so I
changed to 7.0.2.
Is it really a varchar bug?
Anyway, I dumped all the database. When I was restoring it in 7.0.2 I got
these ...

I took a look at the database named 'migrate' (this is where the error
occured),
the tables were all empty. Most of the tables have field like this...

createdate | timestamp | not null default now()

Weird because those timestamps were generated by default now(). Is this an
another bug (timestamp bug)?
Take a look at this ...

migrate=# select version();

PostgreSQL 7.0.2 on i686-pc-linux-gnu, compiled by gcc 2.95.3

migrate=# select '2000-01-05 00:00:60.00+08'::timestamp;
ERROR: Bad timestamp external representation '2000-01-05 00:00:60.00+08'
migrate=# select '2000-11-25 14:05:23.00+08'::timestamp;
?column?

migrate=# create table testing (datetime timestamp);
