Now again im probably just paranoid but when I'm starting a transaction and in it im making more then 4 billions diffrent queries (select,insert,update,truncate...) and then im closing it, its counted as only one transaction right? (should I duck to avoid the manual? ;))

I believe there is a limit on the number of queries in a transaction of
2 or 4 billion (though this may be just in functions).

Ignoring subtransactions, all these queries count as just one transaction.
I am not sure how subtransactions are counted.


If the subtransaction writes at least a tuple, it counts as another
transaction.  Else it doesn't count.


Oh crap I fear that now im in serious troubles....
Where can I read about this limitation? and beside that what if I count the number of queries and every 900,000 or so I create a subtransaction and continue my process with it, will that work or I'm just trying to be a smart ass with the db?

As always thanks alot,
