[Freeswitch-users] [OffTopic] Why PostgreSQL better then MySQL?

I was wondering why developers prefers PostgreSQL other the MySQL? Despite the "thread" issue are the PostgreSQL more preferable in everyday working? I want to integrate a DB for FS, web, and other projects. I already use MySQL, but more and more I see that PostgreSQL is more preferable. I've seen PostgreSQL is used by ArcGIS Server. I didn't like the DB Management interface. In MySQL it is more intuitive. Reading the internet I didn't find a comprehensive conclusion on this PostgreSQL vs MySQL. Also, does PostgreSQL work in fault-tolerance, replication? Thanks. -- Mimiko desu.
