In the hot standby patch, we have this comment in procarray.c:
> It is
> * important that the XLOG_XACT_ASSIGNMENT record contain *all* subxids
> * not just those so far unreported because the sole purpose is to ensure
> * we can remove the xids from KnownAssignedXids.
As the patch stands, that's not what we do. We only include new subxids
in the XLOG_XACT_ASSIGNMENT record that we haven't included in any
previous ones. I think that comment is just obsolete and should be
removed, but am I missing something?
