Autonomous subtransactions

Dear Hackers,

I have written some notes about autonomous subtransactions, which have
already been touched (at least) in two separate threads; please find
them at
 http://wiki.postgresql.org/wiki/Autonomous_subtransactions

It is meant to be an ongoing project, requesting comments and
contributions, rather than a conclusive document.

Thanks,

p.s. The reason for the variation on the name is that there is always    a parent transaction.
