      Description

      The sqlci session below demonstrates the problem. When we do a multi-column BETWEEN where one of the columns is an INTERVAL key column and the values in the BETWEEN predicate for that column are equal, we get a data conversion error.

      >>obey jira.sql;
      >>?section setup
      >>
      >>drop table if exists t1;

      >>create table t1 ( a interval second not null,
      +> b int,
      +> primary key (a) );

      >>
      >>insert into table t1 values ( interval '41' second, 41 );
