Primary key indexes are unique indexes, since SQLite has to enforce the primary 
key being unique.

Howwever, I do not think there can be such a strong penalty for indexes being 
UNIQUE.  I side with David Raymond's opinion that SQLite would not search them 
twice when inserting a new row.  That's merely opinion, though, since I have 
not read the source code.
