postgres configure help

 [postgres@localhost postgresql-8.4.2]$ ./configure -help
 `configure' configures PostgreSQL 8.4.2 to adapt to many kinds of systems.

 Usage: ./configure [OPTION]... [VAR=VALUE]...

 To assign environment variables (e.g., CC, CFLAGS...), specify them as
 VAR=VALUE.  See below for descriptions of some of the useful variables.

 Defaults for the options are specified in brackets.

 Configuration:
   -h, --help              display this help and exit
       --help=short        display options specific to this package
       --help=recursive    display the short help of all the included packages
   -V, --version           display version information and exit
   -q, --quiet, --silent   do not print `checking...' messages
       --cache-file=FILE   cache test results in FILE [disabled]
   -C, --config-cache      alias for `--cache-file=config.cache'
   -n, --no-create         do not create output files
       --srcdir=DIR        find the sources in DIR [configure dir or `..']

 Installation directories:
   --prefix=PREFIX         install architecture-independent files in PREFIX
                           [/usr/local/pgsql]
   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
                           [PREFIX]

 By default, `make install' will install all the files in
 `/usr/local/pgsql/bin', `/usr/local/pgsql/lib' etc.  You can specify
 an installation prefix other than `/usr/local/pgsql' using `--prefix',
 for instance `--prefix=$HOME'.

 For better control, use the options below.

   --bindir=DIR           user executables [EPREFIX/bin]

 Some influential environment variables:

               nonstandard directory <lib dir>
   LIBS        libraries to pass to the linker, e.g. -l<library>
   CPPFLAGS    C/C++/Objective C preprocessor flags, e.g. -I<include dir> if

 Use these variables to override the choices made by `configure' or to help
 it to find libraries and programs with nonstandard names/locations.
