The pg_config utility provides 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 in order to find the respective header files and libraries.
To use pg_config, supply one or more of the following options:
Print the location of user executables. Use this, for example, to find the psql program. This is normally also the location where the pg_config program resides.
Print the location of C and C++ header files.
Print the location of object code libraries.
Print the options that were given to the configure script when PostgreSQL was configured for building. This can be used to reproduce the identical configuration, or to find out with what options a binary package was built. (Note however that binary packages often contain vendor-specific custom patches.)
Print the version of PostgreSQL and exit.
