I don't think there's one easy way to do this, so I wrote the following function to simplify things:

DROP FUNCTION multi_grant(text,text);
CREATE FUNCTION multi_grant(text, text) RETURNS boolean AS '
DECLARE privilidge ALIAS FOR $1;
  user_name ALIAS FOR $2;
  row RECORD;
BEGIN FOR row IN SELECT * FROM pg_class WHERE relkind = ''r'' AND relname !~ ''^pg_''
  LOOP RAISE NOTICE ''GRANT % ON % TO %'', privilidge, row.relname, user_name;
    EXECUTE ''GRANT '' || privilidge || '' ON '' || row.relname || '' TO '' || user_name;
  END LOOP;
  RETURN ''t'';
END;' LANGUAGE 'plpgsql';
SELECT multi_grant('select', 'public');

I suppose that I should quote_ident(row.relname) and quote_literal(user_name), but I'm lazy.
