Patch 2 typos in libpq docs

Both these fixes are to the new "Files" section in the libpq chapter of the
7.3.1 Programmer's Guide. The first fix gets rid of a bogus ">" which
appears in the HTML output at the start of the first paragraph. I have no
idea why DocBook turns the "/>" into an extra >. The second fix is an
obvious typo.
