FWIW, running it on a Linux animal currently requires just a couple steps
1. Download the module:
```sh
curl -LO
https://raw.githubusercontent.com/MankiratSingh1315/pg-bf-client-code/refs/heads/abi-comp-check/PGBuild/Modules/ABICompCheck.pm
mv ABICompCheck.pm build-farm-path/PGBuild/Modules/
```
2. Add it to `modules` in `build-farm.conf`, e.g.,
modules => [qw(TestUpgrade ABICompCheck)],
3. Install the abigail suite; I believe the Debian packages are `abigail-tools` and `libabigail0`
I think that’s it. I use `run_branches.pl --run-all` to test all the current maintenance branches. It does not run
againstmaster.
Best,
