They will be equivalent. text and varchar are the same type internally -- the
only differences are that varchar can have a length (but does not need one),
and that some casts are only defined for text.

If there's really a natural thousand-character limit to the data in question,
use varchar(1000); if not, use text or varchar, whatever you'd like.
