insert a -1 into a bigint ?

Hi All:

I have this table:

# \d seg_id_tmp7
Table "public.seg_id_tmp7"
Column | Type | Modifiers
-----------------+-----------------------------+-----------
customer_srcid | bigint |
show_srcid | bigint |
show_name | character varying |
season_srcid | bigint |
season_name | character varying |
episode_srcid | bigint |
episode_name | character varying |
segment_type_id | bigint |
segment_type | character varying |
segment_srcid | bigint |
segment_name | character varying |
create_dt | timestamp without time zone |

I want to insert some data along with a -1 for two of the bigint
columns. like this:

insert into seg_id_tmp7
( customer_srcid,
show_srcid,
show_name,
season_srcid,
season_name,
episode_srcid,
episode_name,
segment_type_id,
segment_type,
segment_srcid,
segment_name,
create_dt )
select
t8.customer_srcid,
t8.show_srcid,
t8.show_name,
t8.season_srcid,
t8.season_name,
t8.episode_srcid,
t8.episode_name
-1::bigint ,
'none',
-1::bigint ,
'none',
(select start_dt from load_start_date)
from
seg_id_tmp8 t8
;

I've also tried without the ::bigint cast on the above query.

I always get this error:

sql:load_sl_cd_segment_dim.sql:237: ERROR: operator does not exist:
character varying - bigint
LINE 22: -1::bigint ,
^
HINT: No operator matches the given name and argument type(s). You
might need to add explicit type casts.

Thanks in advance for any help, advice, etc..
