Julian Hyde commented on CALCITE-3589:
--------------------------------------
Yeah, it's ironic that a query fails when conformance is set to LENIENT. But it
makes sense.
In LENIENT, Calcite's behavior should be very much like PostgreSQL. If there is
a query that gives a validation error on Calcite-LENIENT and not on PostgreSQL,
or vice versa, please post it.
See also CALCITE-3593. Similar issues in the HAVING clause.

> * group by or having use the above expression
> {color:#172b4d}a simple example is as follows：{color}

> {color:#ff8b00}FROM TEST_KYLIN_FACT{color}
> {color:#ff8b00}GROUP BY SELLER_ID + 1{color}
> {color:#172b4d}will change to {color}
> {color:#ff8b00}SELECT SELLER_ID + 1 AS SELLER_ID, sum(PRICE){color}
