OK that is a syntax I have never seen. But correct we are getting
close.
Noticed that string_to_array does not handle double spaces very well.
If there are double space between the tokens, there is "" (empty string)
in the array returned. Not exactly what I expected.

You almost had it ...
select a_desc, a_desc[1] as name, a_desc[2] as type, a_desc[3] as size
from (select string_to_array(description, ' ') as a_desc from prodlist)
as foo where a_desc[2] = 'B'
