Under >some definitions of "move" you would only have touched the directory entries for the files, which wouldn't give us the information we were looking for.
I took the files from the directory they were in and changed the path.
I guess I don't understand how to copy the contents of the file to accomplish what you are asking.
I presumed that by changing the path of the files the vacuum operation would either skip them or error out saying that they were missing.
Could you help with that please?

I am pretty sure that a vacuum full is eventually what needs to happen since the DB contains useless records and I need the disk space given back to the OS.
But then again I'm no expert with postgres so I am only guessing.
