If your system will forget work on crash, it's not flushed, and you shouldn't report it flushed.


I haven't checked to see if PgJDBC actually exposes separate control of the reported flush position though.  If it doesn't, it really must in order to make replication slots work properly.



Great!

I hope that answers your question then Joe.

Dave, if you'd find it useful to add the explanation I wrote to the docs, please feel free to crib as desired.
