> I faced with a issue that the following query:
> {code:java}
> SELECT ARRAY_CONCAT(ARRAY['1', '2'], array(select 'toast.' || x from unnest(ARRAY['1','2']) x)) {code}
> didn't work, because of:
> {code:java}
> java.lang.IllegalArgumentException: Cannot infer return type for ARRAY_CONCAT; operand types: [CHAR(1) ARRAY, RecordType(CHAR(7) EXPR$0) ARRAY]{code}
> `least restrictive` type inference does not work when one operand is scalar and another is row with one field
