I see there is a isfinite(interval) function. So there must be something
like a infinite interval.

An infinite interval would be yuite handy for me at the moment. But i
have no clue how to make one.

interval 'infinity' does not do the trick. :)


Thank you

On the TODO list:

   o Allow infinite dates and intervals just like infinite timestamps

Looks like it's just a stub :-(


Datum
interval_finite(PG_FUNCTION_ARGS)
{
	PG_RETURN_BOOL(true);
}


Evidently someone planned for infinite intervals a long time ago,
but never got round to it.
