I don't want to kludge up a 2-phase commit support. Any attempt to provide
that must be extremely well thought through :-)
But I would like to know more about PostgreSQL capabilities in the area.
What kind of XA-support is there? Can I read about this somewhere? (I'm
working on an Open Source high-end appserver bundling offer and would of
course like to promote PostgreSQL)
I'm not sure what Tom means when he says "go in and change the code". What
code?
