Tom Lane ee58de1008 Fix memory leak in XMLSERIALIZE(... INDENT). 
xmltotext_with_options sometimes tries to replace the existing
root node of a libxml2 document.  In that case xmlDocSetRootElement
will unlink and return the old root node; if we fail to free it,
it's leaked for the remainder of the session.  The amount of memory
at stake is not large, a couple hundred bytes per occurrence, but
that could still become annoying in heavy usage.

Our only other xmlDocSetRootElement call is not at risk because
it's working on a just-created document, but let's modify that
code too to make it clear that it's dependent on that.
