Hi –
I had a general newbie type question. I am looking for a database that supports replication across datacenters that may be widely distributed.
I understand that Oracle has replication technology through “streams” and “data guard” and would like to understand a little more about the equivalent functionality in postgresql.
Specifically:
1. Does this database support replication across instances of the database?
2. How does it work at a high level?
3. How does it compare to similar functionality in mySQL or Oracle?
4. How reliable is it?
Thanks,
Blake
