Thanks, Greg, i'll give it a try

I'd be quite astonished if sync of XML-fields work, as there is no
XML-equality operator neither in Pg 8.4.4 nor in 9.0B4 and Bucardo
doesn't provide one either
Simple test case:
create table test(id integer primary key, attr xml);
insert into test(id,attr) values (1, '<x>a</x>');
select * from test where id=1 and attr=attr;
ERROR: operator does not exist: xml = xml
LINE 1: select * from test where id=1 and attr=attr;
With type casts it will work, of course:
select * from test where id=1 and CAST(attr AS TEXT)=CAST(attr AS TEXT);
id | attr
1 | <x>a</x>
