Creating table columns from ???

That is, anything but by hand...
It seems that there is a missing function that would be very obvious and
one of the first things available:
  here's what I want to do:
    create table form_two ( <file with names and values> );
  or even better, from perl, or php (I am now using Pg.pm)
    create table form_two ( %hash_with_names_and_values );

How easy does this look?  It seems that this would be though of already,
but the only way I see to make tables is this way...:

create table page_one (
    spacer    text null,
    name    text,
    street    text,
    city    text,
    state    text,
    zip    integer,
    length    integer,
    yorm    text,
    phone    text,
    opt    text,
    fax    text,
    email    text,
    ceo    text,
    senior    text,
    comp    text,
    d_o_c    date,
    webPG    text,
    n_o_b    text,
    pge    integer,
    spacer2    text null
);
(doesn't this seem a bit cumbersome?)

And this is the smallest out of eleven forms (a small web site indeed.)
So what do all those people do with huge sites, and bigger forms?  There
must be something I'm missing.  Please, someone point it out to me, as
this project goes to the funders june 8.
I appreciate everyone's help in all matters, thank you.
