Re: comparing with oracle

Hi Bruno,
Thanks for the reply. Still my questions were unanswered. Pl could
anyone give a solution.

1. Is there any way I can generate archive log in postgres
2. Is it possible to run the postgres in standby mode (like Oracle stnd
by server) and apply the archive logs

Thanks and regards,
Sachdev
