Been searching for a way to do this, but haven't found what I was hoping
to find. Is there any way in pl/pgsql to test a text value to see if it
would be a valid interval without having to try and store in a field? In
a trigger, I'd like to test a NEW text type field. Right now, I have
just the following to generate an error...
test := NEW.textfield::interval;
I'd like to test the field and RAISE EXCEPTION if not valid interval.
