postgresql - 为什么我在 postgres 上复制功能时出现美元报价错误

Question

我有一个带有 COPY TO A CSV FILE 的 Postgres 函数的问题，我有美元报价错误

这是功能

CREATE OR REPLACE FUNCTION save_audit_deletions(IN table_name text) 
   RETURNS void AS 
   $body$ 
   DECLARE    
       interval INT; 
   BEGIN        
       COPY (SELECT * FROM table_name WHERE backup = 1) 
          TO'/var/audiobays/logs/audit/table_name_deletions_(date-days).csv' CSV DELIMITER ',' HEADER; 
    END 
    $body$ 
    LANGUAGE plpgsql;

这是错误

Error executing: CREATE OR REPLACE FUNCTION save_audit_deletions(IN table_name text) RETURNS void AS
$body$
DECLARE
BEGIN
    EXECUTE FORMAT ('COPY (SELECT * FROM %s WHERE backup = 1) TO ''/var/audiobays/logs/audit
