Reusing the ReadRecord infrastructure in situations where the code that wants
to do so is not tightly integrated into xlog.c is rather hard and would require
changes to rather integral parts of the recovery code which doesn't seem to be
a good idea.

Missing:
- "compressing" the stream when removing uninteresting records
- writing out correct CRCs
- separating reader/writer

I'm disappointed to see that there has been no progress on this patch since last commitfest. I thought we agreed on the approach I championed for here: http://archives.postgresql.org/pgsql-hackers/2012-09/msg00636.php. There wasn't much work left to finish that, I believe.

Are you going to continue working on this?
