It's an isolation issue but if you're coming from Mongo I'd broadly guess it's not one you're going to trigger. Also, look at their other analyses ... they're very detailed and upfront about serialization isolation issues in a lot of huge databases/datastores.
Noteworthy:
"In most respects, PostgreSQL behaved as expected: both read uncommitted and read committed prevent write skew and aborted reads."
- castorp 6y agoPostgres does not support read uncommitted
- petergeoghegan 6y agoTechnically it does. You can ask for read uncommitted mode, though you'll just get read committed mode. This is correct because you're getting the minimal guarantees that you asked for. The SQL standard allows this.
