I have looked into the patches.

Shouldn't "CLANG" be "LANG"?

Currently "make postgres*.pdf" generates the pdf file even if there's
a "not available in font" error while generating it. With the patch
the pdf file is removed in this case. I'm not sure if this is an
improvement because there's no way to generate such a pdf file if
there's such a warning. Printing "Found characters that cannot be
displayed in PDF" is good, but I'd prefer let users decide whether
they retain or remove the pdf file.

You don't need to include the patch for configure. Committer will
generate configure when it gets committed. See the discussion:
