4# This replacement script for the pg_config binary is based on the original pg_config
5# shell script, which was removed from PostgreSQL's codebase in 2004:
6# https://github.com/postgres/postgres/commit/cc07f8cfe73f56fce1ddda4ea25d7b0b6c4f0ae9
7#
8# The main reason for removal was the ability to relocate an existing installation, which
9# is exactly the one feature that we are trying to work around in nixpkgs.
10# Going back to a shell script is much better for cross compiling.
