I figured I could save the values whenever they are going to change, and
restore them if the subtransaction aborts. This seems to work fine
(lightly tested).
I still have to figure out how to handle allocation for string vars, but
I thought I'd post the patch for others to see. Please let me know if
it's too ugly. (This patch misses the pieces in xact.c and xact.h but
I'm sure the concept is clear.)
I'll post a full patch once the missing deferred trigger stuff works.
With the patches I posted to inval.c I think this fulfills the
requirements, barring the performance issues raised.
Comments?
