That's hard to compete with. By default tables created in MySQL are
non-transactional...and can thus operate with much less overhead . In a
"query only" - or when you are only inserting rows in a table -
situation, this is quite fast. As a transactional database, I'm not
sure how well PostgreSQL could compete with that...
