Description:

Hi,

In https://www.postgresql.org/docs/current/history.html it is written "With
over two decades of development behind it".
But since "The implementation of POSTGRES began in 1986" according to the
same document, it should now be "With over three decades of development
behind it".

Regards,
Pierre
