Re: BUG #1517: SQL interval syntax is accepted by the parser,

Roy> It would be

    Roy>    INTERVAL '1 1' DAY TO HOUR

Actually, it would be any one of the following:

   INTERVAL '1 1' DAY TO HOUR
   INTERVAL '1 1:00' DAY TO MINUTE
   INTERVAL '1 1:00:00' DAY TO SECOND
   INTERVAL '25' HOUR
   INTERVAL '25:00' HOUR TO MINUTE
   INTERVAL '25:00:00' HOUR TO SECOND
   INTERVAL '1500' MINUTE
   INTERVAL '1500:00' MINUTE TO SECOND
   INTERVAL '90000' SECOND

all of which are equivalent to the postgres interval

   INTERVAL '1 day 1 hour'

but all of them have (in ANSI SQL) disitinct data types.

At this point you may decide that ANSI intervals are (to put it
politely) somewhat overcomplex... :-)
