Everything in contrib/ is considered to be under the same license as the rest of the distribution. (A few of them have their own copyright text, but it's not substantially different in meaning from the main copyright notice. This is also true of bits of the core server, actually.) Extensions you get from elsewhere might have different copyrights though. regards, tom lane
