Thesis on PostgreSQL

Part of my final year thesis involves creating a
database using PostgreSQL. As a way of documentation,
is it correct to say that PosgreSQL belongs to the
fifth generation of database management systems? Where
does MySQL fall into? The fourth generation?

Thanks,

Newton Eyinagho
