是否可以将Postgresql数据库从Amazon RDS复制到另一个Amazon RDS？

Question

I have a Postgresql database in my Amazon RDS and I want to replicate it into another Amazon RDS so I can bifurcate the connections depending on the situation but keeping the same data.

Besides, it would be very nice if I could replicate just some tables from the main database and be able to do INSERTS into the non-replicated tables from the second database. Like this:

**DB1**      **DB2**
DB1.table1   DB2.table1
DB1.table2   DB2.table2
DB1.table3   DB2.table3
DB1.table4   DB2.table_log
DB1.table5

Replicate table1 , table2 and table3 from DB1 to DB2 , not replicate table4 and table5 and still be able to INSERT into table_log .

Is this possible?

You can use the AWS Database Migration Service to replicate specific tables from one database to another, and you can even alter the schema when you replicate if you want. Be sure to create a change data capture (CDC) replication task so changes in the source database get immediately pushed to your target database.
