Re: Regression tests fail with musl libc because libpq.so can't be loaded

I can see how that could work around the problem, because the library 
would already be available in the default library path / rpath and 
LD_LIBRARY_PATH would not be needed.

However, this would only be a workaround for the specific case of 
running the regression tests, not a solution. Using LD_LIBRARY_PATH, as 
documented, would still not be possible.

In my case, I am just using docker images with Alpine to easily 
reproduce the problem. I am building with NixOS / nixpkgs' pkgsMusl. The 
order of check and install phases can't be changed there, AFAICT. The 
workaround I use right now is to temporarily patch rpath of the postgres 
binary - this will be reset during the install phase anyway. This works, 
but again is not a real solution.

Best,
