Ouch, I see your point:

    uninstall:
            rm -f '$(DESTDIR)$(htmldir)/html/'* $(addprefix  '$(DESTDIR)$(mandir)'/man, 1/* 3/* $(sqlmansectnum)/*)

That Makefile assumes your man pages are in a Postgres-specific
directory, rather than shared with other applications.  I am unclear how
to fix this as we don't actually have a list of files to uninstall;
rather, we just copy every file we have generated during the install.

I have added a Makefile comment about this undesirable behavior in case
we ever find a way to fix it.  The cleanest way would be to build the
docs as part of the uninstall, get a list of those files, then delete
the files from the install and the man directories.
