I think he's having trouble finding out what the table name is in the
first place.

Maybe you can use something like this to get the name:

select relname from pg_catalog.pg_class where relkind = 'r' and
relname like 'some%thing';

where 'some%thing' is the table name with % for the part you don't know.

Using "pg_dump -s" to dump the schema might be another way to find the name.

If that doesn't help, you could perhaps get the table name like the
using a perl/python/whatever program and then in the same program
execute a DROP command using the table name you got previously.

I'd make sure you have a good backup first, though, just in case you
accidentally drop the wrong table.
