pg_config
   The view pg_config describes the
   compile-time configuration parameters of the currently installed
   version of PostgreSQL. It is intended, for example, to
   be used by software packages that want to interface to
   PostgreSQL to facilitate finding the required header
   files and libraries. It provides the same basic information as the
   pg_config PostgreSQL client
   application.
  
   By default, the pg_config view can be read
   only by superusers.
