Hi
I am sending some POC - it does support XPATH and XMLTABLE for not UTF8
server encoding.
In this case, all strings should be converted to UTF8 before call libXML2
functions, and result should be converted back from UTF8.
I found some previous experiments https://marc.info/?l=pgsql-bug
s&m=123407176408688
Note: I got some information so used xmlNodeDump function is deprecated -
so we should to replace it too sometime.
Regards
Pavel
