pow() on struct literal returns random result

[Dimitar Misev]

SELECT power({ 13c, 115c, 212c }, 0us)

result { inf, 1, 1 }

SELECT power({ 13c, 115c, 212c }, 0d)

result { 1, 1, inf }

SELECT pow({ 13c, 115c, 212c }, 0)

result { 1, 1, inf }

I executed the last one 10 times with

for i in $(seq 10); do rasql -q 'SELECT pow({ 13c, 115c, 212c }, 0)' --out string | grep Result; sleep 1; done

and got

  Result element 1: { 1, 1, 1 }
  Result element 1: { 1, 1, 1 }
  Result element 1: { 1, 1, 1 }
  Result element 1: { 1, 1, 1 }
  Result element 1: { 1, 1, 1 }
  Result element 1: { -nan, 1, 1 }
  Result element 1: { 1, 1, 1 }
  Result element 1: { 1, 1, 1 }
  Result element 1: { 1, 1, 1 }
  Result element 1: { 1, 1, inf }
