That's easy:

MySQL has type mediumint
PostgreSQL has transactions

MySQL allows 'and' as string markers
PostgreSQL has views

MySQL has case insensitive compare
PostgreSQL has referential integrity

MySQL has support for 0000-00-00 dates
PostgreSQL has subqueries

MySQL has 'drop table if exists'
PostgreSQL has multiversion concurrency control

etc.

See? Equal. I hope my sarcasm is not too overstated.
