it exists a transaction id called XID, you can't get it via sql

though, you need to make a c function and invoke GetTopTransactionId()
(or GetCurrentTransactionId() in versions prior to 8.0)

I've read a little about problems with overlapping XID and how they were 
resolved. I don't understand everything but it seems that XID could be 
decreased after vacuum, could it?
