You sure you did not actually do an UPDATE without a WHERE?


What does your table definition look like?

                                          Table "public.companies"
    Column    |         Type          | Collation | Nullable |                  Default

--------------+-----------------------+-----------+----------+--------------------------------------
 company_nbr  | integer               |           | not null | nextval('companies_org_nbr_seq'::regclass)  company_name | character varying(64) |           | not null | '??'::character varying
  url          | character varying(64) |           |          |
  email        | character varying(64) |           |          |
 industry     | character varying(24) |           | not null | 'Other'::character varying  status       | character varying(20) |           | not null | 'Opportunity'::character varying
  comment      | text                  |           |          |
  ea_nbr       | integer               |           |          | 0
  ea_amt       | numeric(10,2)         |           |          | 0.00
Indexes:
     "organizations_pkey" PRIMARY KEY, btree (company_nbr)
Foreign-key constraints:
