Hi All

I tried to run a vacuum against the pg_largeobject table but unfortunately, I ran out of space on my WAL logs causing the vacuum to abort.
The issue I have now is that it has created copies of the data files (I think it was the temp table (vacuum_1) that gets created when vacuum runs. How do I get rid of these files if there is no reference to them in the pg_class table? Also, if I rerun the vacuum will it delete these files.

Regards
Ian
