pg_dumpall is going to need to run against a Postgres server not just a data directory.
Adrian, Of course. Yet it's the data directory that's written to the .sql file.
If both your old and new machines are on the same network, why not just point the 11.1 pg_dumpall(on the new machine) at the 9.5 server running on the old machine?
The old host is running 10.5. Haven't tried to run an application on one host using data on another host. I'll look at which tool will do that. Thanks, Rich
