Hi Folks ,

can anyone please help?
i have a to drop a check contstraint from a column. eg

tradein_clients=# \d t_a
           Table "t_a"
   Column   |  Type   | Modifiers
------------+---------+-----------
 company_id | integer |
 exp        | text    |
 imp        | text    |
Check constraints: "$1" (length(imp) > 1)
                   "aaaaaq" (length(imp) > 1)

Can i remove to contraints thru ALTER TABLE or similar commands.
I have read the docs for ALTER TABLE but the command described is 
not working for me.

=======================================================
ALTER TABLE [ ONLY ] table
        DROP CONSTRAINT constraint { RESTRICT | CASCADE }
========================================================

Regards
Mallah.
