Is it possible to import raw data directories in a cluster (Debian)?

Hi,

During an upgrade of by customer he managed to drop the original cluster
as the first step. As soon as he saw his error he broke off the
pg_dropcluster by ctrl-c. Of course he has no useful backups, But it
appears that the directories of the database he wants to restore are
still on disk and untouched by his upgrade.

Is it possible to import the data in the directories somehow so that
they are fully functional databases?

TIA
