psql -l gives bad output

Hi, I am running PostgreSQL 7.1.3 on Solaris 8.

The output of psql -l seems wrong. In the following, their are 2
databases named "pay-test" and one named "/usr/local/pgsql/bi". I can
dropdb one of the pay-tests but not the other, and I can't dropdb the
/usr/local/pgsql/bi database. I can't access these databases either.
vacuumdb -a gives me an error too, when attempting to access these
databases.

# psql -U postgres -l
List of databases
Database | Owner
---------------------------------+----------
pay | postgres
pay-test | postgres
pay-test
/usr/local/pgsql/bi | postgres
template0 | postgres
template1 | postgres
(5 rows)

Does anyone have any ideas?

Thanks,
Jeff
