Do we really want to mention 8.3 in current versions of the docs?

Hi,

do we really want to reference version 8.3 in current docs?
https://www.postgresql.org/docs/current/row-estimation-examples.html -> "The 
outputs shown are taken from version 8.3"

The examples seem to be more or less fine,.

Regards
Daniel
