Re: Problem building both Python 2 and 3 into Postgres 9.4.4?

That worked, thank you.

The Tip in 43.1 did not explain in that much detail. I searched but could
not find that explained anywhere in the docs. Your paragraph would be
a nice enhancement to the tip.

I do not think you can do it like this:

> make distclean
> ./configure --with-openssl --with-libxml
--with-libxslt --with-python PYTHON=/usr/bin/python
> make
> ./configure
--with-openssl --with-libxml --with-libxslt --with-python
PYTHON=/usr/bin/python3
> make
> make install

You need to configure and make one way, then
install, then make distclean,
reconfigure
and remake the other way, then make install in only the
src/pl/plpython directory.  The recipe as you
have it will end up with
only one installed
copy of plpython, not two, and I'm not real sure that
that copy will be correctly built for either
case.
