It appears that if you update a record more than once in the same PostgreSQL transaction, PostgreSQL is going to re-check all the constraints on the table. ** THIS IS THE PART WHERE THE BLACK MAGIC HAPPENS ** We combine the setting of the default value of stock.move.unit_factor in the same UPDATE query to avoid the constraint re-check; it saves approximately 60% of the SQL running time in my case. ** ... AND NOW YOU CAN SAY: WHAT THE F...?! ** Thanks to @rco-odoo for the tip; he knows it from the wise @nseinlet. X-original-commit: 8e47e2f605309c8ed0d5509f7bb070528d8f32c4
