pg_config1Applicationpg_configretrieve information about the installed version of PostgreSQL>pg_config--bindir--includedir--includedir-server--libdir--pkglibdir--configure--versionDescription>
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:
>
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 header files of the client interfaces.
>
Print the location of C header files for server
programming.
>
Print the location of object code libraries.
>
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.)
>
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.
If more than one option (except for Notes
The option is 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 . 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
