This is probably too esoteric to be worked on yet, but for this to
be useful for us we would need to pass the resulting files through
pg_clearxlogtail and gzip in an automated fashion. And we would
need to do regular log file archiving in parallel with it.
As background, our databases around the state archive to a directory
which is then pushed via rsync to a "dumb" backup location in the
same room as the database server (we're lucky to have rsync on the
target of this copy; any other executable is out of the question),
and the same directory is pulled via rsync to a central location.
We would be interested in using streaming replication to a tool such
as you describe for the copy to the central location, but since we
would still be forcing a wal-file switch once per hour we would need
the current capability to shrink an "empty" file from 16MB to 16kB
using the above-mentioned tools.
Also, a the ability to limit bandwidth would be a nice feature for
us, preferably in a way which could be changed on the fly.
If you could keep the development "friendly" to such features, I may
get around to adding them to support our needs....
