Здравствуйте. Выполняю скрипт и не пойму, почему выводит эту ошибку:

 
DROP TABLE budget;
 
CREATE TABLE budget (
  entry_id bigint NOT NULL,
  financial_year character varying(4) NOT NULL,
  ....
  oktmo_code character varying(255),
  orfk_entry_id bigint,
  parent_id bigint,
  CONSTRAINT budget_pkey PRIMARY KEY (entry_id)
);
 
 
CREATE TABLE budget_to_budget_account (
  budget_entry_id bigint NOT NULL,
  budget_account_entry_id bigint NOT NULL,
  budget_account_type character varying(255),
  CONSTRAINT budget_to_budget_account_pk PRIMARY KEY (budget_entry_id, budget_account_entry_id),
  CONSTRAINT uk_ij96hqd7kx45xsad3jsvi1m5l UNIQUE (budget_account_entry_id),
  CONSTRAINT bgt_bgt_acct_fk1 FOREIGN KEY (budget_entry_id) REFERENCES budget(entry_id) DEFERRABLE
);

И для последней таблицы пишет: ОШИБКА: отношение "budget" не существует
