Hi,

I've been reviewing HS/SR and have a couple of thoughts/notes:

- The recovery_done_command is not documented (that I can find, at
least) in the documentation.
- There is (presently) no way to have PostgreSQL's standby node "clean
up" unneeded WAL files (the %r parameter for archive_command).  I saw
some talk about adding a 'archive_cleanup_command' to recovery.conf, but
that doesn't seem to work (yet).  I think this should be listed as a
to-do item on the wiki for this application (or if it was added after
the alpha4 release, noted as a completed item.)  Without a way to
cleanup archives, the wal archive could end up getting very large, and
even fill up the file system it is on...
