I'm actually fighting with some interesting things now with error handling, I wan't aware I had to do my own retry on deadlocks.
Ugh, it's just one of those days I feel like I'm not as good at this as I thought I was.
It all depends where the deadlocks are though, you can easily achieve them in the Go code as well as the database queries.
I'm not around much today as I'm with a client this morning and lunch, but if you're stuck later I may well be in https://gophers.slack.com/ . Happy to help out if I can, as I'm sure most others will be.
