Regular reindexing is so inexpensive compared to vacuum, I recommend adding it in as part of your regular maintenance. At the very least, it's unlikely to ever be that severe again unless you don't reindex for an equally long period of time. Come to think of it, an auto-reindex option might be nice in core someday.
