For example (not heavily tested!)

CREATE OR REPLACE FUNCTION grant_all(text) RETURNS TEXT AS '
DECLARE
   rel record;
   sql text;
BEGIN
   FOR rel IN SELECT pg_catalog.quote_ident(c.relname) AS relname FROM
pg_catalog.pg_class c WHERE c.relkind = ''r'' AND c.relnamespace NOT IN
(select oid from pg_catalog.pg_namespace where nspname like ''pg\_%'') AND
pg_catalog.pg_table_is_visible(c.oid) LOOP
     sql := ''grant all on '' || rel.relname || '' to '' || $1;
     RAISE NOTICE ''%'', sql;
     EXECUTE sql;
   END LOOP;
   RETURN ''OK'';
END;
' LANGUAGE 'plpgsql';

create user foo;
select grant_all('foo');

HTH,
