Ok, I have logical replication up-and-running (I guess - seemed to simple to be 
working. Shouldn’t it be complicated, requiring many steps and configuration 
changes?), maxing out one CPU core on each machine (more or less), and showing 
network throughput of around 15M. If DU changes are to be believed, it’s 
transferring data at about 0.8GB/minute, implying something like a 8 hour 
transfer time.

Of course, since it is replication, it has the benefit that any data that comes 
in during that 8 hour window should also be replicated, after which the two 
systems should remain in sync allowing for zero (or nearly so) downtime 
cutover. Which is nice.

Any gotchas I need to be aware of during this initial transfer window, such as 
WAL files building up on the source machine?
