Any reason behind the switch to v2?

No reason to stay away from v1, really. The v2 rand.N is generic, so it can do time.Duration without casts; that was nice.
The behavior of these parameters is independent of OpenTelemetry. This refactor is part of a larger series to make the Postgres log directory configurable.

⛏️ we're doubling % to escape in case the prefix/suffix have % -- but ours don't, right?
and if someone forgot/missed that we're handling this and doubled the % originally, we'd quadruple the %?

Right. Escaping occurred to me as I was writing the test. I expect the postgres package to know about these details, while other packages don't.

Yep. If someone thinks to escape before calling, their test would show the wacky number of escapes.
