Function 执行postgresql函数时出错

我有一个简单的功能：

CREATE OR REPLACE FUNCTION soundavity.perform_search_by_serie_name( in_search_text   text )
RETURNS bigint[] AS

$BODY$

DECLARE 
match_id bigint[];  

BEGIN

SELECT id INTO match_id
FROM soundavity.tv_serieslist_tbl
where id IN (   
        SELECT id 
        FROM table
        WHERE to_tsvector('english', name) @@ to_tsquery('english', in_search_text)
        )
LIMIT 10;   


RETURN match_id;

END;

但是当我试着

select perform_search_by_serie_name('something');

Postgres返回：

ERROR:  array value must start with "{" or dimension information
CONTEXT:  PL/pgSQL function soundavity.perform_search_by_serie_name(text) line 8 at    SQL statement

错误在哪里？

'SELECT id'返回一组bigint而不是bigint数组。 试试这个：

DECLARE 
    match_id bigint[] = '{}';
    rid bigint;
BEGIN
    for rid in
        SELECT ... -- without INTO
    loop
        match_id:= array_append(match_id, rid);
    end loop;
RETURN match_id;

“SELECT id”返回bigint not bigint数组的集合。 试试这个：

DECLARE 
    match_id bigint[] = '{}';
    rid bigint;
BEGIN
    for rid in
        SELECT ... -- without INTO
    loop
        match_id:= array_append(match_id, rid);
    end loop;
RETURN match_id;
