pg_config — retrieve information about the installed version of PostgreSQL
Synopsis
pg_config [option...]
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
psqlprogram. This is normally also the location where thepg_configprogram resides. --docdir-
Print the location of documentation files.
--htmldir-
Print the location of HTML documentation files.
--includedir-
Print the location of C header files of the client interfaces.
--pkgincludedir-
Print the location of other C header files.
--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 might also be installed in this directory.)
--localedir-
Print the location of locale support files. (This will be an empty string if locale support was not configured when PostgreSQL was built.)
--mandir-
Print the location of manual pages.
--sharedir-
Print the location of architecture-independent support files.
--sysconfdir-
Print the location of system-wide configuration files.
--pgxs-
Print the location of extension makefiles.
--configure-
Print the options that were given to the
configurescript 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.) See also the examples below. --cc-
Print the value of the
CCvariable that was used for building PostgreSQL. This shows the C compiler used. --cppflags-
Print the value of the
CPPFLAGSvariable that was used for building PostgreSQL. This shows C compiler switches needed at preprocessing time (typically,-Iswitches). --cflags-
Print the value of the
CFLAGSvariable that was used for building PostgreSQL. This shows C compiler switches. --cflags_sl-
Print the value of the
CFLAGS_SLvariable that was used for building PostgreSQL. This shows extra C compiler switches used for building shared libraries. --ldflags-
Print the value of the
LDFLAGSvariable that was used for building PostgreSQL. This shows linker switches. --ldflags_ex-
Print the value of the
LDFLAGS_EXvariable that was used for building PostgreSQL. This shows linker switches used for building executables only. --ldflags_sl-
Print the value of the
LDFLAGS_SLvariable that was used for building PostgreSQL. This shows linker switches used for building shared libraries only. --libs-
Print the value of the
LIBSvariable that was used for building PostgreSQL. This normally contains-lswitches for external libraries linked into PostgreSQL. --version-
Print the version of PostgreSQL.
-?--help-
Show help about pg_config command line arguments, and exit.
If more than one option is given, the information is printed in that order, one item per line. If no options are given, all available information is printed, with labels.
Notes
The options --docdir, --pkgincludedir, --localedir, --mandir, --sharedir, --sysconfdir, --cc, --cppflags, --cflags, --cflags_sl, --ldflags, --ldflags_sl, and --libs were added in PostgreSQL 8.1. The option --htmldir was added in PostgreSQL 8.4. The option --ldflags_ex was added in PostgreSQL 9.0.
Example
To reproduce the build configuration of the current PostgreSQL installation, run the following command:
eval ./configure `pg_config --configure`
The output of pg_config --configure contains shell quotation marks so arguments with spaces are represented correctly. Therefore, using eval is required for proper results.
