Probably some part of your application, or a function you're calling from there, is setting a different timeout.
That's what I thought, but I'm using the same db handle and only sending plain SQL on base tables. Only triggers, rules and foreign keys should be in play I think...
I don't remember setting a statement timeout in a trigger, that seems kind of crazy.
