PostgreSQL vs MySQL - Mailing list pgsql-advocacy

We ran across this article comparing the two-leading open-source dbms'.

Would you mind commenting on the cons (e.g., no data partioning capability, large-database-related issues, non-commercial (like Veritas or Tivoli) HA support, etc.) that the author wrote about PostgreSQL?

Thanks,
