The default isolation level is read committed mode, whereas the bug in question only affected applications that use serializable mode. You have to ask for serializable mode explicitly; if you're not, then you cannot possibly be affected by the bug. (Perhaps you should consider using a higher isolation level, but that would be equally true with or without this bug.)
