target with inclusive to  false at the next xid after the insert, we end up
with the same DELETE/DROP directory behaviour which is quite confusing. One
have to choose the xid-1 value with inclusive behaviour to lake it work.

I assume this is the right first thing to document the behaviour. And give
some examples on this.

Maybe we could add some documentation in the xlog explanation and a warning
in the recovery_target_time and xid in guc doc ?

If there are better places in the docs let us know.

Thanks
