Re: patches for items from TODO list - Mailing list pgsql-hackers

minor nit: the null attribute should take XMLSchema boolean type values: 
{true, false, 1, 0}

More importantly, how do you handle array or record type fields? If they 
are just opaque text I don't think that's what I at least would want 
from XML output routines.
