Question

我正在为我的postgresql数据库创建一个函数，并且需要将6位字符串编码为ascii字符。虽然我得到错误：格式不正确的数组文字。我该如何解决？

为解决这个问题，我已经研究过使用右括号和单引号。但是我还没有成功。

`CREATE OR REPLACE FUNCTION example(payload bit varying) 
RETURNS text AS $str$ 
DECLARE 
    str text := ''; 
    len int; 
    i int; 
    tbl text[] := '{@,A,B,C,D,E,F,G,H,I,J,K,L,M,N,O,P,Q,R,S,T,U,V,W,X,Y,Z,[,\\,],^,_," ",!,"\"",#,$,%,&,‘,(,),*,+,",-,.,/,0,1,2,3,4,5,6,7,8,9,:,;,<,=,>,?}'::text[];
BEGIN
        .....
END; 
$str$ LANGUAGE plpgsql 
IMMUTABLE 
;`

Below the error message:
ERROR:  malformed array literal: `"@,A,B,C,D,E,F,G,H,I,J,K,L,M,N,O,P,Q,R,S,T,U,V,W,X,Y,Z,[,\\,],^,_," ",!,"\"",#,$,%,&,‘,(,),*,+,",-,.,/,0,1,2,3,4,5,6,7,8,9,:,;,<,=,>,?}"

LINE 1: SELECT '{@,A,B,C,D,E,F,G,H,I,J,K,L,M,N,O,P,Q,R,S,T,U,V,W,X,Y...
               ^

如何修复出现错误的函数：“格式错误的数组常量”“详细信息：输入的意外结尾”？
