What I'd like to see in 7.2 is a WAL API with the following
functionality:
* Get the latest transaction in the WAL
* Get transaction, transId, from the WAL
* Was a given transaction rolled back?
What I don't want to have to worry about is all the internals needed for
writting the log. I shouldn't need to know if a new seagment was
created, when and where checkpoints are made, etc.
Perhaps there could be a small library for just reading stuff the WAL
file?
The second suggestion I have is one I alreay alluded to and would offer
to help work on. Namely replication for Postgres. Given the simple API
listed above I already have a roughed out design for replication deamon.
Just some suggestions.
