Bug reference: 7844
Logged by: fduerr

PostgreSQL version: 9.2.2
Operating system: Debian
Description:

Up until 9.1

select (xpath('/z/text()', ('<z>' || 'AT&amp;T' || '</z>')::xml))[1];

returned 'AT&T'
9.2 returns 'AT&amp;T'

Is it a bug or a feature?
Is there a function to decode xml-entities?

Does anyone have a comment on this?
