Actually it's not limited to the usage of INTERVAL SECOND, I am writing
a PostgreSQL driver for our 4GL virtual machine...
I need to store all possible Informix INTERVAL types such as:
INTERVAL MONTH(8) TO MONTH
INTERVAL DAY(8) TO MINUTE
INTERVAL SECOND TO FRACTION(5)
... etc ...
...
If PostgreSQL is not able to store months > 11, hours > 23 and minutes
or seconds > 59, it looks like I will need to deal with PostgreSQL's
INTERVAL YEAR TO MONTH
INTERVAL DAY TO SECOND(5)
... and make conversions, to store all possible Informix INTERVALs...
