我有以下.load文件
LOAD DATABASE
FROM mysql://user:password@remotelocation/mydbname
INTO postgresql://user@localhost/dbname
WITH data only,truncate, workers = 8, concurrency = 1
SET maintenance_work_mem to '128MB',
work_mem to '12MB',
search_path to 'mydbname'
CAST type datetime to timestamptz drop default drop not null using zero-dates-to-null,
type mediumint with extra auto_increment to bigserial,
type date drop not null drop default using zero-dates-to-null,
type tinyint to boolean using tinyint-to-boolean;
我收到错误
Database error 2BP01: cannot drop constraint random_pkey on table random because other objects depend on it.
我可以在不丢弃密钥的情况下加载数据吗?我也尝试将disable triggers
参数添加到with子句中,但这也不起作用。
我正在使用postgre 9.6而pgloader的版本号是3.3.2
答案 0 :(得分:0)
有两个项目解决了我的问题。第一个是默认打开include drop
参数,所以我需要添加include no drop
参数,其次最近修复了一些错误,所以我还需要从源代码编译pgloader。
