postgres删除然后pg_dump转储删除的数据

Question

Using postgres 9.5.5

I'm running a script that does a

DELETE FROM hugetable

where the table 'hugetable' is large and has many millions of rows. I then do a pg_dump on the database and the dump still contains all the data in the table 'hugetable' that I thought was just deleted. I've tried using TRUNCATE on the table but we keep getting locking issues. What are some of the solutions to this? Running VACUUM on the table after I run the DELETE?

您回滚了删除的事务，或者您从未提交过该事务，但该事务仍处于打开状态。
