I have an old production instance, let's call it A, that I need to decommission soon.

I've created a pair of new instances, B and C, with B replicating to C, following this procedure:

https://wiki.postgresql.org/wiki/Streaming_Replication

But B and C have no data yet. I need to transfer all data from A into B.

Can I daisy-chain streaming replication? In other words, temporarily setup replication like this:

A ==> B ==> C

And after the transfer is done, just remove A from the scheme.
