One way to deal with this would be to have a boolean flag in the table like
"deleted". Update that flag to true, and have a partial index "where deleted".

Then your daemon can quickly query "select file_name where deleted", process
the files and actually complete the deletion. All your other queries need to
test "where not deleted" or go through a view with a clause like that.
