Catch overflow when rounding intervals in AdjustIntervalForTypmod. Previously, an interval microseconds field close to INT64_MAX or INT64_MIN could overflow, producing a result with not even the correct sign, while being rounded to match a precision specification.
This seems worth fixing, but not worth back-patching, in part because the ereturn() notation doesn't exist very far back.
