I have added the following paragraph to the FAQ:
<P>CHAR() is best when storing strings that are usually the same length. VARCHAR() is best when storing
variable-lengthstrings, but you want to limit how long a string can be. TEXT is for strings of unlimited length,
maximum1 gigabyte. BYTEA is for storing binary data, particularly values that include NULL bytes.</P>
