i already made a change in the PR yesterday, did you check the code diff. did you test the latest version.
Also i don't agree in removing the not null, all the other databases have it.

i followed this path

• downloaded the latest staging
• installed with mysql no pdo
• installed the com_patchter
• applyed PR [SQL errors] When installing languages (backend/installation) in PDO Strict mode/Sql Azure joomla/joomla-cms#11763 with the last changes (as it is now)
• dropped all tables in the database
• deleted the configuration.php
• added the strict mode to pdomysql.php at line 155

//$this->connection->query("SET @@SESSION.sql_mode = '';");
$this->connection->query("SET @@SESSION.sql_mode = 'STRICT_TRANS_TABLES,NO_ENGINE_SUBSTITUTION';");

• double checked that all changes in the PR [SQL errors] When installing languages (backend/installation) in PDO Strict mode/Sql Azure joomla/joomla-cms#11763 are correctly in place
• started a new installation with mysql pdo strict mode as a database
• select the no data for basic multiligual install
• double check that PR are corretclty applyied as db schema on chenged tables checked with phpmyadmin
• click on extra step install languages
• got the sql error

p.s.
PDO sould be considered as a different DB .... what is valid for other's DB is not valid with PDO

i've uploaded a "dirty" video on youtube https://youtu.be/BNXSUJqJVSs with a step by step of the process i've followed hope this may help more

@alikon i just saw your video yet again and discovered you get the error BEFORE installating any language. Minute 7:25 to end of your video

You get the error afer clicking "installa languages" to go to the language select.

This is different from the error i solved: the error when you selected a language and press install.
