There is some confusion here. I'll try to clarify, if the error was on my part. I don't change the yum configuration on my CentOS 4 servers. Consequently, they remain pointed at whatever repository(ies) come stock with the OS. Consequently, I don't see a postfix-mysql package available to yum. Consequently, I have to compile MySQL support into Postfix myself from source. :)
