Question

在postgresql中：

第1步：

我收到了错误：

ERROR:  duplicate key value violates unique constraint "question_pkey"
DETAIL:  Key (id)=(11) already exists.
STATEMENT:  INSERT INTO question (content,uid,answer_count,answer_users,view_count,status,created_at,updated_at,attach) values ($1,$2,$3,$4,$5,$6,$7,$8,$9) returning *
LOG:  statement: DEALLOCATE pdo_stmt_00000001

第二步：

我称之为句子：

master=# ALTER SEQUENCE question_id_seq RESTART WITH 110702;

步骤3：

插入一个问题，但是question_id是11而不是我期望的110703。

我的表格如下：

CREATE TABLE question (
    id serial NOT NULL PRIMARY KEY,
    content text, 
    uid int NOT NULL DEFAULT 0, 
    attach text NOT NULL DEFAULT '',
    answer_count int NOT NULL DEFAULT 0, 
    status smallint NOT NULL DEFAULT 0
);

添加我的服务器日志：

LOG:  statement:
LOG:  statement: insert into "public"."question" ( "uid", "content") values ( '1', '1')
ERROR:  duplicate key value violates unique constraint "question_pkey"
DETAIL:  Key (id)=(30) already exists.
STATEMENT:  insert into "public"."question" ( "uid", "content") values ( '1', '1')
LOG:  statement:
LOG:  statement: ALTER SEQUENCE question_id_seq RESTART WITH 110706
LOG:  statement:
LOG:  statement: insert into "public"."question" ( "uid", "content") values ( '1', '1')
ERROR:  duplicate key value violates unique constraint "question_pkey"
DETAIL:  Key (id)=(31) already exists.
STATEMENT:  insert into "public"."question" ( "uid", "content") values ( '1', '1')

我错了，\ d问题显示我不使用quesiton_id_seq，但使用question_id_seq1。谢谢mu

为什么postgresql得不到正确的ID？
