 Description   

According to the documentation "engine_condition_pushdown" default value is ON :

https://mariadb.com/kb/en/mariadb/documentation/optimization-and-tuning/query-optimizations/optimizer-switch/

Whereas it defaults to OFF on a fresh install of MariaDB 10.0.14 (with no optimizer_switch option in cnf files).

I don't know if it had ever been enabled by default in MariaDB, even in 5.5, I couldn't find a version where it was on.

Given that it's deprecated now, maybe it's for the best (see
https://blog.mariadb.org/mariadb-10-1-1-engine_condition_pushdown-flag-deprecated/).

Documentation needs to be fixed.

This was the MySQL default, and since it first appeared there, their default was listed. Documentation has been amended. I'll double check all the other defaults and clarify that the default is the MariaDB default in case of difference.
