Guessing /home/postgres/data*/userqueries/ is the location of your
tablespace, not the cluster directory.

The -d and -D need to point at the cluster directory, which will be
something like :

/var/lib/postgresql/9.3/main

No, you need to point to the correct directory.

See here for more information:

http://www.postgresql.org/docs/9.4/interactive/pgupgrade.html

Or use pg_upgradecluster:
