PG_CONFIG(1) PostgreSQL Client Applications PG_CONFIG(1)NAMEpg_config - retrieve information about the installed ver-
sion of PostgreSQL
SYNOPSISpg_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 nor-
mally 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 config-
uration, or to find out with what options a binary
package was built. (Note however that binary pack-
ages 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 information is printed in that order, one item per
line.
NOTES
The option --includedir-server 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 --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 configura-
tion information did not exist.
HISTORY
The pg_config utility first appeared in PostgreSQL 7.1.
