Using 8.4.1. How can I
1) Get the transaction id of the oldest serializable transaction and the
next transaction?
2) A list of all active transactions
I have searched the docs and tried Google but I must not be using the
right terminology.
Also, am I correct in assuming that vacuuming is not blocked by a long
running read committed transaction but only by the oldest serializable
transaction?
Any references to relevant documentation would be appreciated.
