Peter Eisentraut f73999262e tablefunc: Reject negative number of tuples passed to normal_rand()
The function converted the first argument i.e. the number of tuples to
return into an unsigned integer which turns out to be huge number when
a negative value is passed.  This causes the function to take much
longer time to execute.  Instead, reject a negative value.

(If someone really wants to generate many more result rows, they
should consider adding a bigint or numeric variant.)

While at it, improve SQL test to test the number of tuples returned by
this function.
