How can I make them constantly create restore points? Once I create
recover.conf it creates recover.done but what about those new queries
that comes after that? Do I have to re-create recover.conf? Or how do I
achive constant logging to slaves? This issue is not clear in the
documentation http://www.postgresql.org/docs/8.3/interactive/continuous-archiving.html

The only way that is at all supportable right now in that regard is to use PITR:
http://www.postgresql.org/docs/8.3/interactive/continuous-archiving.html
That does NOT allow you to query the backup nodes; in order to do so,
you must activate them, which amounts to failing over to the backup
node.
If your system doesn't have a stable schema, that seems like a
problem...
