Bug reference:      5534
Logged by:          Mike Fowler
Email address:      mike@mlfowler.com
PostgreSQL version: 9.0beta2
Operating system:   Linux 2.6.31-14-generic #48-Ubuntu SMP
Description:        IS DOCUMENT predicate errors instead of returning false
Details:

IS DOCUMENT should return false for a non-well formed document, and indeed
is coded to do such. However, the conversion to the xml type which happens
before the underlying xml_is_document function is even called fails and
exceptions out. I've mentioned this on -hackers with message ID
