Well, I didn´t know where was the problem exactly, then ...
The entire script to see that problem is 

create domain public.i32 as integer;

CREATE FUNCTION public.fntextonumero(ftext text, finteger public.i32)
RETURNS boolean
    LANGUAGE sql STABLE
    AS $$
  SELECT ftext = finteger::text;
$$;
CREATE FUNCTION public.fntextonumero(finteger public.i32, ftext text)
RETURNS boolean
    LANGUAGE sql STABLE
    AS $$
  SELECT ftext = finteger::text;
$$;

CREATE OPERATOR public.= (
    FUNCTION = public.fntextonumero,
    LEFTARG = text,
    RIGHTARG = public.i32
);
CREATE OPERATOR public.= (
    FUNCTION = public.fntextonumero,
    LEFTARG = public.i32,
    RIGHTARG = text
);

Then that script I´ve sent you this morning.
This way I think you can get the problem. Is this a Postgres problem ? Well,
I created these operators because Firebird accepts comparisons between
numeric and text values, and as we converted from that ... I found a way to
continue comparing them. The problem ocurred now because the IN operator.
