All right, so I misspelled Bucardo (also Mammoth...), and the company's name is Command Prompt (please get someone to work on that incomprehensible logo - I went back and looked at it and still have no clue what it means :-).

Now how about some serious answers relating to my questions?

Dimitri, thanks for your answer. I don't need to replicate TO the staging server (this is where the changes happen) but rather FROM the staging server TO the Web (query) servers. I think my description wasn't clear enough. Currently the staging DB changes daily as new records are inserted to it (would have liked to use COPY instead, but I believe that's only useful for bulk loading the whole DB, not appending to it?). Those changes need to be reflected on the Web servers. Today this is done via dump-copy files-restore of the whole DB (we shut down each Web server DB while restoring it, obviously), and I we are looking for a better way.

I would truly appreciate specific suggestions and pointers/references ("some trigger based asynchronous replication" doesn't help much...).

Also is my understanding of PITR limitations correct?

Thanks,

-- Shaul

A new desert, Buchardo CMO:

Two shots of brandy
One shot of rum
Vanilla Ice cream
Cherries

Blend to perfection.
