that will at least establish that the command is being found.
OK - --help on the 9.3 lists help options
In your original post you said you have a 9.3 instance and a 9.4 instance.
>From your post I would say the 9.3 instance was installed by the one click installer from EDB and the 9.4 from Bitami, is that correct?
Correct.
So do you know where the 9.4 binaries are installed?
If by binaries, you mean the program files they are installed C:\Bitnami\wappstack-5.5.30-0\postgresql\bin
Per previous posts you want, whenever possible, to us a newer version of pg_dump to move a database from an older version(9.3) to a newer one(9.4). Therefore you should do your dump and restore using the pg_dump.exe and pg_restore.exe from the Bitanami bin directory. I would cd to the above directory and do:
pg_dump -V pg_restore -V
to make sure the programs are found and are the 9.4 versions.
It appeared to work with this method, but it has now been running for almost 4 hours with no result. The db is not that large (probably v. small by most standards) and the .out file is ~200mb
What is running, the dump or the restore?
The restore - I can see the dump .out file that was created at 16hr in the postgresql/bin folder
