Nested Transactions/Savepoints

Hi, <br />   I may be a little off -topic asking this here, but then i thought you are the guys working on the
bleedingedge and can provide me better insight. <br /><br /> My query is- <br /> When can we see Savepoints and Nested
Transactionsin postgresql officially in a stable release? <br /><br /> AFAIK in 7.3 release savepoints and nested
transactionsare not allowed, plz correct me if i am wrong. <br /><br /> Also can hackers point me to some resource
regardingthe latest work being done in this area and its current status. <br /><br /> Thanks a lot <br /><br /> regards
