 # 5.4 PostgreSQL
 
-PostgreSQL is an object-relational database management system available for many platforms including Linux, FreeBSD, Solaris, Microsoft Windows and Mac OS X. It is released under the MIT-style license, and is thus free and open source software. It's larger than MySQL, because it's designed for enterprise usage like Oracle. So it's a good choice to use PostgreSQL in enterprise projects.

 ## PostgreSQL drivers

 I'll use the first one in my following examples.

 	res, err := stmt.Exec("astaxie", "研发部门", "2012-12-09")
