Dmitry Sysolyatin updated CALCITE-4999:
---------------------------------------
    Description: 
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
