* This program reports various pieces of information about the
* installed version of PostgreSQL. Packages that interface to
* PostgreSQL can use it to configure their build.
*
* This is a C implementation of the previous shell script written by
* Peter Eisentraut <peter_e@gmx.net>, with adjustments made to
* accommodate the possibility that the installation has been relocated from
* the place originally configured.
