Re: pow support for pgbench

There is a typo in the XML doc:

Please check that the documentation compiles.

I'm at odds with having the integer version rely on a double pow(), even
if it works. I think that there should be a specific integer version which
does use integer operations. From stack overflow, the following is
suggested:

int ipow(int base, int exp)
{
int result = 1;
while (exp)
{
if (exp & 1)
result *= base;
exp >>= 1;
base *= base;
}

return result;
}

The integer version should be when x & y are integers *AND* y >= 0.

if y is a negative integer, the double version should be used.
