Here is a little PL/pgSQL sniplet, I used to delete all tables from
schema public:

----- snip-snap -----

CREATE OR REPLACE FUNCTION dropit() RETURNS integer AS'
DECLARE
    numberoftables integer := 0;
    tabletodrop RECORD;
BEGIN
    FOR tabletodrop IN SELECT tablename from pg_tables where
schemaname=''public'' LOOP
        numberoftables := numberoftables + 1;
        RAISE NOTICE ''Droping table %'', tabletodrop.tablename;
        EXECUTE ''DROP TABLE public.''
            || tabletodrop.tablename;
    END LOOP;
    RETURN numberoftables;
END;
' LANGUAGE plpgsql;

----- snip-snap -----

You execute it by "select dropit();" on the psql commandline.

But be warned, it will drop _all_ tables in the used schema.
