--------------------------------------

             Summary: Support PostgreSQL's interval syntax
                 Key: CALCITE-5654
                 URL: https://issues.apache.org/jira/browse/CALCITE-5654
             Project: Calcite
          Issue Type: Improvement
          Components: core
            Reporter: Tim Nieradzik

Support day-to-second intervals using PostgreSQL's syntax:
select INTERVAL '2 weeks 3 days 4 hours 5 minutes 6 seconds 7 milliseconds'
select INTERVAL '-30 day'

These should be equivalent to:
select INTERVAL '17 04:05:06.007' DAY TO SECOND
select -INTERVAL '30 00:00:00.000' DAY TO SECOND
