I know this is fairly widely known, but I wanted to make sure that it was properly logged so that it could be fixed. I did a search, and I didn't find the bug on this forum, so I wanted to make sure it was known.
Basically, the PQ increase racial ability is not terribly useful, and is probably broken. All it does is increase a planet's PQ rating; it doesn't create new tiles for use by the player.
The PQ rating is useful towards morale, but that bonus is not nearly enough to be worth 8 racial creation points. 8 points would be more inline for an ability that turns a planet with 4 tiles into one with 5, and turns a planet with 15 tiles into one with 18. That's a pretty substantial advantage, well worth 8 points. Getting a morale bonus on a class 9 or above planet instead of a class 11 or above isn't really worth it.
Either the PQ ability should be adjusted to cost fewer points or it should actually provide tiles.
