I am not trying to start a mysql vs postgres war so please dont
misunderstand me .... I tried to look around for mysql vs postgres articles,
but most of them said mysql is better in speed. However those articles were
very old so I dont know about recent stage. Please comment !!!


It is my experience that MySQL is faster under smaller load scenarios. Say 5 - 10 connections only doing simple SELECTS. E.g; a dymanic website.

It is also my experience that PostgreSQL is faster and more stable under
consistent and heavy load. I have customers you regularly are using up to 500 connections.

Note that alot of this depends on how your database is designed. Foreign keys slow things down.

I think it would be important for you to look at your overall goal of migration. MySQL is really not a bad product "IF" you are willing to work within its limitations.

PostgreSQL is a real RDMS, it is like Oracle or DB2 and comes with a comparable feature set. Only you can decide if that is what you need.
