I assumed the try was purely so you could 'catch' things. And did not
mean run it in a subtransaction (without the try block it still runs
in one).
Personally, I was looking more at:

Which to me says if SPI has an error we get a nice error object back,
that also lets you do the normal exception catching dance (if thats
what you are in to...) and translates IMO better to how plpgsql works
("exception when unique_violation").

Sounds more like a savepoint?
