Answer
TEXT stores unlimited variable-length text, whereas VARCHAR can enforce a maximum length. Performance difference is minimal.
Quick Answer
TEXT and VARCHAR are functionally identical in PostgreSQL - both store unlimited length strings with the same performance. VARCHAR(n) enforces a maximum length (inserts longer strings fail). TEXT has no length limit. Unlike other databases, PostgreSQL TEXT is not slower than VARCHAR. Use TEXT unless you have a specific business reason to enforce a maximum length.
