Обсуждение: rc4, PostgreSQL-installer on WinXP: problems with plpython

1. Python as PL was greyed out an could not be installed again via the
installer - contrary to rc3, where PL/Python's  installation was offered
and did work.

2. When trying to install plpythonu with creatlang, this was not
possible because of something like "error in python.dll: python23.dll
not fount"
    On my system python23 was replaced with python24 some days ago.
    Only when I copied python23.dll to c:/windows/system32, createlang
did create plpythonu.
    It was not sufficient to copy python23.dll to
C:\Programme\PostgreSQL\8.0.0-rc4\lib

    If PostgreSQL needs python23.dll, the installer should have it,
should copy it into C:\Programme\PostgreSQL\8.0.0-rc4\lib and
createlang.exe should first search it there.
    Other programms as winide, and natlink, which too still use
python23.dll do indeed have there own copy with them and have it in
there own privat lib-directory.

This means that you don't have python23.dll on your system.

Python24 is not currently supported by the binary installer (see the
installation instructions).

Correct. It might work if you put it in 8.0.0-rc4\bin though. Or add the
directory where it's already in to your PATH.

I *think* we require a full python installation, not just the DLL file.
I'm not 100% sure on that. It currently supports Python23, which is also
in the installation instructions. If someone can confirm that we need
only the DLL, we can definitly include it in our distribution.
So - can someone who knows enoughh aboyt plpython speak up on that one?
