want to drop corrupt db

After a db restore failed for reasons having to do with lack of disk
space, when I try to restart the DB, I get...

dfg_suse> postmaster -D /proj/cad_sserv/cellibcmp/daveg/Postgres/DB -i >

HINT: This probably means that some data is corrupted and you will have
to use the last backup for recovery.

If the DB is trashed, how can I just delete it and start from scratch?

Thanks
