Bug reference: 4769
Logged by: Arjen Nienhuis
Email address: a(dot)g(dot)nienhuis(at)gmail(dot)com
PostgreSQL version: 8.3.7
Operating system: Ubuntu 8.10 and 9.04
Description: xmlconcat produces invalid xml values -> data corruption
Details:
'<!DOCTYPE html><html/>' is a valid xml document but not a valid xml
fragment. xmlconcat does not check for this:
SELECT xmlconcat('foo', xmlparse(DOCUMENT '<!DOCTYPE html><html/>'));
xmlconcat
---------------------------
foo<!DOCTYPE html><html/>
The result is an invalid xml value that can end up in a table.
==============================================
=> SELECT version();
version
----------------------------------------------------------------------------
-------------------------
PostgreSQL 8.3.7 on x86_64-pc-linux-gnu, compiled by GCC gcc-4.3.real
(Ubuntu 4.3.3-5ubuntu4) 4.3.3
(1 row)
libxml2 version is 2.6.32.dfsg-5ubuntu4
=============================================
I tried to test this with 8.4 but the ubuntu ppa has depency problems.
