+# Based on upstream's own wheel build at this tag (the python-manylinux job of
+# .github/workflows/packaging.yml and ci/scripts/python_wheel_unix_{build,relocate}.sh):
+#   https://github.com/apache/arrow-adbc/blob/apache-arrow-adbc-24/.github/workflows/packaging.yml
+# which builds libadbc_driver_postgresql.so via CMake against vcpkg's static
+# libpq, then setup.py copies it into the package and the relocate script
+# retags + auditwheel-repairs the resulting py3-none-any wheel into a
+# platform one. This narrows that to Linux riscv64: vcpkg has no riscv64
+# binary cache, so libpq comes from the manylinux image's own libpq-devel
+# instead, and the relocate script's retag step is reproduced inline since it
+# isn't vendored as a package file we can invoke directly. See
+# build-adbc-driver-manager.yml for why the checkout uses the Go module tag.
