You can create a cast like this:
create or replace function bool_to_text (boolean)
returns char
strict
language sql as '
select case
when $1 then \'t\'
else \'f\'
end;
';
create cast (boolean as char(1))
with function bool_to_text(boolean)
as implicit;

Better check again --- there has never been a standard cast from bool to
text. Sure you didn't install a custom one in your 8.1.0 database?
