Don't think so. You need those functions and noone has written
them officially.

The former is easy, something like:

create function text(bool) returns text as 'select case when $1 then
''true'' else ''false'' end;' language 'sql';

should suffice.

I'm not entirely sure this is entirely safe for the latter, but you can
try :)

create function numericout(numeric) returns int as 'numeric_out' language
'internal';
create function text(numeric) returns text as 'select
textin(numericout($1));' language 'sql';
