It looks like you’re trying to build for Intel but the libpq.5.15.dylib library is built for Apple silicon. Are you building on Intel? If so, you’ll need to tell your compiler driver to build for Apple silicon.

As to how you do that, that depends on whether the gcc is your command is actually GCC or whether you’re using Clang via the gcc alias:

If it’s the former, I can’t help you. I don’t maintain expertise in GCC.
If it’s the latter, you do this by passing in the ‘triple’ via the -target option.
