The Halloween problem is that it is a challenge for the database if you’re updating a field that is also in the WHERE clause of the same query.
I just saw a presentation from someone about how in SQL Server he recommended writing changes to a temp table and then writing them to the table as being much more efficient.
Does Postgres handle this problem efficiently, or should we follow a similar strategy?
