o Support ISO INTERVAL syntax if units cannot be determined from

The SQL standard states that the units after the string
specify
the units of the string, e.g. INTERVAL '2' MINUTE should
return '00:02:00'.
The current behavior has the units
restrict the interval value to the specified unit or unit

interpret
'1:30' as '1 hour, 30 minutes'.

The SQL standard supports a limited
number of unit combinations and doesn't support unit names

the range of units supported, e.g. PostgreSQL supports
'1 year 1
