Reason: I want to update the bigger table in Postgresql, which will take a lot of time . So I want to replicate the table asynchronously which can run in background (sync the data , as well update the column which needs to be updated) . Once that is done, I will drop the older, and use the new.
I am trying to find a way copy the table asynchronously to the same database . What will be the best solution ?
I am looking for is a way to do that londiste. It looks table replication on different dbs seems simple. But while trying to add both provider and consumer, I am getting the below error.
