Does postfix natively included in Centos 7 support mysql?

I read this post,mentioned:

The version of Postfix included in the main CentOS repository does not include support for MariaDB; therefore, you will need install Postfix from the CentOS Plus repository.

But,In a newly install(from ISO) Centos7 server,run postconf -m, the result as below:

[root@localhost ~]# postconf -m
btree
cidr
environ
fail
hash
internal
ldap
memcache
mysql
nis
pcre
proxy
regexp
socketmap
static
tcp
texthash
unix

I can see mysql,does postfix natively included in Centos 7 support mysql?
