Mihai Budiu commented on CALCITE-6345:
--------------------------------------
I see a test in IntervalTest.subTestIntervalYearNegative() that seems to imply
that this behavior is by design:
{code:java}
f.wholeExpr("INTERVAL '100' YEAR")
.fails("Interval field value 100 exceeds precision of YEAR\\(2\\)
field.*");
{code}
However, at least in Postgres this expression is legal. Why is this test
expected to fail?
