Hi!

use "alter table ??? drop constraint ???"

example:

create table asdf (userid text, foreign key (userid) references 
person(userid) on delete cascade);

\d asdf
     Table "public.asdf"
  Column | Type | Modifiers
--------+------+-----------
  userid | text |
Foreign Key constraints: $1 FOREIGN KEY (userid) REFERENCES 
person(userid) ON UPDATE NO ACTION ON DELETE CASCADE

alter table asdf drop constraint "$1";

Regards,
Patrik Kudo
