Re: Table seems empty but its size is in gigabytes

Now my big table statistics shows tuples inserted and its size is in order of gigabytes, but a simple SELECT has no rows, is there any way to recover the data in this table?

​Do you want to recover the dead data or the space ​that it consumes?

to free the disk space, use...

    vacuum full tablename;

I don't know how to reclaim tuples that were written but rolled back.
