为什么SimpleJdbcCall不返回所有行？

Question

我有这个postgresql函数：

drop function public.get_comments;
CREATE OR REPLACE FUNCTION public.get_comments(in_post_id character varying)
 RETURNS table (
    cid varchar,
    ccontent text,
    cmnt_count bigint 
 )
 LANGUAGE plpgsql
AS $function$
declare
--  arr_comments record [];
    rec record;
    postRecord record;
    tagLabel varchar;
begin
    return query
    select id, "content", (
                select count(*) from comments_reply where comment_id=c.id
            ) as reply_count
            from post_comments c
            where c.post_id = '863550630468626253';
END
$function$
;

当我直接使用select public.get_comments('863550630468626253');调用它时，它总共返回七行。但是当我从春季应用out调用它时，只有一行，

SimpleJdbcCall jdbcCall = new SimpleJdbcCall(dataSource).withProcedureName("get_comments")
            .withCatalogName("public");
    Map<String, Object> out = jdbcCall.execute(postId);
    out.entrySet();
