xpath_string namespace issue... - Mailing list pgsql-general

I'm not sure what I'm missing here... :)

select xpath_string($xml$<?xml version="1.0" ?>
<f:foo xmlns:f="foo">
  <f:bar>baz</f:bar>
</f:foo>
$xml$
,'//f:bar/text()')

This does not give me back "baz" as I was expecting it to... How does one clue-in the xpath functions to the namespaces
inthe XML document?
