add support and test for gen_random_uuid()

[davidwheeler123]

Adds support for gen_random_uuid() postgres function, which comes out of the box since v13

I'm unable to run the build on my local (m1 mac) so I haven't been able to test it. Is there a way to build on m1 mac?

It should work out of the box on M1.

BTW regarding M1, see #3857. I was wrong, you need to download a compatible jdk 8 by yourself, eg azul.

I still can't get it to compile locally
I'm now getting this in gradle

Execution failed for task ':runtime:tvosSimulatorArm64Test'.
> Error while evaluating property 'device' of task ':runtime:tvosSimulatorArm64Test'.
   > Failed to calculate the value of task ':runtime:tvosSimulatorArm64Test' property 'device'.
      > Xcode does not support simulator tests for tvos_simulator_arm64. Check that requested SDK is installed.

I've installed XCode and the tvos platform but the error persists.

intellij is giving this error

The project is using an incompatible version (AGP 7.4.0) of the Android Gradle plugin. Latest supported version is AGP 7.4.0-beta02

I'm not an android dev, don't really know what it's talking about
