"pg_config Executable Not Found" Issue: Resolved

While you mentioned pg_config is in your PATH and accessible via the command line, the installation process still fails due to an apparent discrepancy.

To resolve this issue, ensure that you have the postgresql-devel package installed on your system. This package typically contains the pg_config utility. On Debian/Ubuntu-based systems, it's called libpq-dev, while on Centos/Fedora/Cygwin/Babun, it's libpq-devel. Once installed, the pg_config utility should be accessible during the installation process.
