Due to some code reshuffling, xmlconcat(NULL) will crash in 8.3 and 8.4.
The pfree(buf.data) in ExecEvalXml() frees a buffer that is actuall
only initialized in the XMLFOREST case. So then the xmlconcat(NULL)
falls through to the pfree() it crashes. I have attached a patch for
8.3 and 8.4 to clean this up.
