    [ https://issues.apache.org/jira/browse/CALCITE-6454?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17862504#comment-17862504 ] 

Norman Jordan commented on CALCITE-6454:
----------------------------------------

GREATEST and LEAST functions should support arrays once CALCITE-6454 is resolved.

>             Project: Calcite
>          Issue Type: Improvement

> The comparison operators <, <=, >, >=, =, <> are not implemented for arrays. Here is an example query:
>  
> {code:java}
> SELECT array[2, 2] > array[1, 1]; {code}
> [This page|https://popsql.com/learn-sql/postgresql/how-to-compare-arrays-in-postgresql] describes how the comparisons  work in PostgreSQL.
>  
> Check if the comparison operators for arrays exist in other DB engines.
