Update "screenshot" in Tutorial

The following documentation comment has been logged on the website:

Page: https://www.postgresql.org/docs/9.6/static/tutorial-accessdb.html
Description:


In the "screenshot" on

https://www.postgresql.org/docs/9.6/static/tutorial-accessdb.html

the version() is
"PostgreSQL 9.6beta1 on i586-pc-linux-gnu, compiled by GCC 2.96, 32-bit"

and SELECT current_date returns a date from 2002

This is clearly not what a "normal user" would get on his computer. I'm not
sure whether version 9.6 would even compile with gcc 2.96...

Please update the version /compiler information and the "current_date" 

Regards,
Mike
