Use the provided constructor functions:
regression=# select box(point(1,2),point(3,4));
box
-------------
(3,4),(1,2)
(1 row)
As a general rule, converting something to text and back is not the way
to convert data from one type to another; if it's not a really
outlandish conversion, there'll be a function or cast to help.
