IMO, that's not a good idea. I see it this way, for any function first
the input args have to be validated. If okay, then follows the use of
those args and the main functionality. I can also see pg_promote(),
which first does the input timeout validation throwing error if it is
<= 0.

We can retain the existing behaviour.

Agreed!

Thanks
