Attached is an updated patch for XML functionality, which subsumes all
earlier patches on the subject. This includes a data type with format
checking, and functions to mangle values. For the moment, I have cut
out the inessential stuff such as xpath. The included regression test
file xml.sql shows some of the things that work.
This patch already covers most of the parser work. What is left
hereafter is adjusting all the corner cases, the escaping rules, and
the various XML parser behaviors.
Use configure --with-libxml to build.
