I don't think two very minor bugs in Hot Standby, reported and fixed 7
days apart is any indication of instability. It isn't the "daily bugs
reported" you suggested. Personally, I think it indicates quite the
opposite - if those are the only bugs I can find now, I'm ecstatic.

I think your argument does apply to Streaming Rep, at this point. We
should consider releasing Alpha4 and then later going to Beta.

My point of view expressed here is not built in a few seconds, it is
built on discussion and feedback over 18 months. The conflict issue was
discussed by me with hackers at the May 2008 dev meeting. It should be
improved upon in this release and it has been the main issue concerning
the full range of people I have discussed HS with.
