如何將APSchduelder sqlite恢復到Postgres

Question

我正在從sqlite遷移到postgres。

這裏是dumpfile.sql

PRAGMA foreign_keys=OFF; 
BEGIN TRANSACTION; 
CREATE TABLE apscheduler_jobs (
    id VARCHAR(191) NOT NULL, 
    next_run_time FLOAT, 
    job_state BLOB NOT NULL, 
    PRIMARY KEY (id) 
); 

我試圖像APScheduler通過從該回購https://github.com/jarekwg/django-apscheduler/blob/master/django_apscheduler/migrations/0001_initial.py

然後，SQL命令是跟隨遷移SQLite的確實創造了相同的模式：

CREATE TABLE "apscheduler_jobs" ("id" varchar(255) NOT NULL PRIMARY KEY, "next_run_time" NUMERIC(11,2) NOT NULL, "job_state" bytea NOT NULL); 
CREATE INDEX "apscheduler_jobs_83d3412e" ON "apscheduler_jobs" ("next_run_time"); 
CREATE INDEX "apscheduler_jobs_id_9f0be75e_like" ON "apscheduler_jobs" ("id" varchar_pattern_ops); 

我準備了以下數據庫：

CREATE DATABASE apscheduler; 
GRANT ALL PRIVILEGES ON database apscheduler to uih; 

我的問題： 請參閱此網址。我試圖鑄造輸入是一個bytea https://www.postgresql.org/docs/9.4/static/functions-string.html

INSERT INTO "apscheduler_jobs" 
VALUES('c891c2288a0f4585b169a335dd57b971',

什麼是正確的語法restore我sqlite轉儲文件postgres？

更新： 我有它新的問題。第二行來自手冊INSERT。我有點擔心它。我會嘗試再次回到這裏。

更新： 十進制是沒有問題的

Answer 1

我不知道如果我得到你的權利。我截斷了你的長字符串，並從二進制變爲bytea並插入了值。是不是你嘗試做？：

t=# create table b5 (bta bytea); 
CREATE TABLE 
t=# insert into b5 select X'800495EA0100'; 
ERROR: column "bta" is of type bytea but expression is of type bit 
LINE 1: insert into b5 select X'800495EA0100'; 
          ^
HINT: You will need to rewrite or cast the expression. 
t=# insert into b5 select E'\\x800495EA0100'; 
INSERT 0 1 
t=# select * from b5; 
     bta 
---------------- 
\x800495ea0100 
(1 row) 

爲您插入到工作，它應該是什麼樣子：

INSERT INTO "apscheduler_jobs" 
VALUES('c891c2288a0f4585b169a335dd57b971', 
     1.51008480006619596482e+09,
