Обсуждение: how to re-configure postgresql-rpm version

I downloaded postgresql 7.2.1 - rpm version, installed it to my Linux machine
and inputted some of my data in postgresql.  Now I would like to re-configure
my postgresql server by increasing --enable-local and
--enable-multibyte=UNICODE options.  How should I do?
I found all document talking about re-configure tar.gz version not rpm.  The
main point is that I can not find the ./configure file from rpm version.
Please help me. I'm a newbie on Linux and Postgresql.
Thanks in Advance.

The "tar.gz" version you're talking about must be the "source" version, ie the
version you have to "compile", "build".
Hence the ./configure call, that will "configure" (heh, who said computer
science terms are often misleading ?) your build and installation.
The rpm version is the binary version, where "almost everything" is done for
you. You won't find any ./configure or Makefile in a binary version.
If you want to tweak your postgreSQL install at build-time, get the source
version instead and follow README and INSTALL files instructions.
(Basically, you will "./configure --with-all-your-favorite-options=enabled",
"make", "make install").

PS: DO uninstall the rpm version first.

It will be slightly long story. You should obtain SRPM file first,
then extract the SRPM file in '/usr/src/redhat/SOURCES'
(in RedHat Linux for example) like as,

/usr/bin/rpm2cpio (SRPM file) | /bin/cpio -i

You could add the compile options to file named 'postgresql.spec',
and, the comand below will build a new rpm package.

rpm -ba --target foo postgresql.spec
