postgresql vs mysql

[gustavo halperin <ggh(dot)develop(at)gmail(dot)com>]

 Hello

I  have a friend that ask me why postgresql is better than mysql.
I personally prefer posgresql, but she need to give in her work 3 or 4 
strong reasons for that. I mean not to much technical reasons. Can you 
give help me please ?

 Thank you,
  Gustavo
