Need to Remove Constraint, but Don't Know How - Previous attempts failed - Mailing list pgsql-general

Hi,

I'm sorry but I didn't create the table.  I fiddled with the table for a while and didn't get what I expected.  So I'm
goingto ask the community. 

Can some one tell me which constraint would case me the "duplicate key into unique index users_pkey"?  I'd like to
removethat constraint. 

Here is the create:
CREATE TABLE "users" (
        "user_id" integer DEFAULT nextval('users_pk_seq'::text) NOT NULL,
        "user_name" text DEFAULT '' NOT NULL,
        "email" text DEFAULT '' NOT NULL,
        "user_pw" character varying(32) DEFAULT '' NOT NULL,
        "realname" character varying(32) DEFAULT '' NOT NULL,
        "status" character(1) DEFAULT 'A' NOT NULL,
        "shell" character varying(20) DEFAULT '/bin/bash' NOT NULL,
        "unix_pw" character varying(40) DEFAULT '' NOT NULL,
        "unix_status" character(1) DEFAULT 'N' NOT NULL,
        "unix_uid" integer DEFAULT '0' NOT NULL,
        "unix_box" character varying(10) DEFAULT 'shell1' NOT NULL,
        "add_date" integer DEFAULT '0' NOT NULL,
        "confirm_hash" character varying(32),
        "mail_siteupdates" integer DEFAULT '0' NOT NULL,
        "mail_va" integer DEFAULT '0' NOT NULL,
        "authorized_keys" text,
        "email_new" text,
        "people_view_skills" integer DEFAULT '0' NOT NULL,
        "people_resume" text DEFAULT '' NOT NULL,
        "timezone" character varying(64) DEFAULT 'GMT',
        "language" integer DEFAULT '1' NOT NULL,
        "third_party" integer DEFAULT 1 NOT NULL,
        "personal_status" character(32),
        "bemsid" integer,
        "sensitive_info" character(64),
        "reason_access" text,
        "organization" text,
        Constraint "users_pkey" Primary Key ("user_id")
);

Here is my table:

                                         Table "users"
