            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.

            Then do:

            pg_dump -Fc -p 5432 -U postgres -f irll_project.out irll_project

            pg_restore -U postgres -p 5532 irll_project.out


        that last needs to have -d newdbname     where newdbname has already
        been created, for instance, by...


    Aah, my mistake. Yes you need to specify the database to get the
    restore to work properly. Also explains why there is nothing in the
    logs.


OK - with the inclusion of stating the dbname the restore works, but not
correctly: what is restored is 24 of 48 tables and 1 of 22 views from
one schema and no tables from the other schema.

A log appeared at 0:08 last night (I'm at GMT +1), which I've attached.
Plus, I did the dump and restore again this morning and have attached
the text from the windows shell if that helps

Well the one from this morning shows(I did not look through whole thing) you restoring over existing database objects. I would say at this point the  best thing you can do is get to a known state on the 9.4 cluster you want to dump to. I am assuming you are not doing anything with the database irll_project on the 9.4 server at this point, correct?

If so, for the below keep track of exactly what you do and the order you do it, in case you need to post back here.

1) On the 9.4 server, while logged into another database on the server, say postgres do:

DROP DATABASE irll_project;

2) Using the 9.4 version of pg_dump dump the 9.3 version of irll_project.

3) Using the 9.4 version of pg_restore restore irll_project to the 9.4 server.
