I just tried make uninstall. I did:
sudo make uninstall
which goes:
make -C doc uninstall
make -C src uninstall
make -C sgml uninstall
rm -f '/opt/local/share/doc//postgresql/html/'* '/opt/local/share/man'/man1/* '/opt/local/share/man'/man3/* '/opt/local/share/man'/man7/*
/bin/sh: /bin/rm: Argument list too long
So it tries to delete all my manpages. (/opt/local is a macports install). Yes, I realize installing into /opt/local was not such a hot idea to begin with. but I knew I had make uninstall, so I could easily back off, right?
