Re: Using postgres.log file for replication

Hi Scott,

Thanks for the replay,

It is almost impossible to use any of the replication tools mostly because the 2 dbs are not on the same network (live and testing environments)... I don't intend to use this for high availability. I am using Sequoia and PITR for that...

I only intend to use it to replicate a live database for testing purposes on another network...

Thanks again,
Ioana
