pg_config(1)

NAME

       pg_config  -  retrieve information about the installed version of Post-
       greSQL

SYNOPSIS

       pg_config { --bindir | --includedir | --includedir-server | --libdir  |
       --pkglibdir | --configure | --version }...

DESCRIPTION

       The  pg_config utility prints 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.

OPTIONS

       To use pg_config, supply one or more of the following options:

       --bindir
              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.

       --includedir
              Print the location of C header files of the client interfaces.

       --includedir-server
              Print the location of C header files for server programming.

       --libdir
              Print the location of object code libraries.

       --pkglibdir
              Print the location of dynamically loadable modules, or where the
              server would search for them. (Other architecture-dependent data
              files may also be installed in this directory.)

       --configure
              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.)

       --version
              Print the version of PostgreSQL and exit.

       If more than one option (except for --version) is given,  the  informa-
       tion is printed in that order, one item per line.

NOTES

       The  option  --includedir-server  was  new  in PostgreSQL 7.2. In prior
       releases, the server include files were installed in the same  location
       as  the  client  headers,  which  could  be  queried  with  the  option
       --includedir. To make your package handle both  cases,  try  the  newer
       option first and test the exit status to see whether it succeeded.

       In releases prior to PostgreSQL 7.1, before the pg_config came to be, a
       method for finding the equivalent  configuration  information  did  not
       exist.

HISTORY

       The pg_config utility first appeared in PostgreSQL 7.1.
