Hi John Scalia,

I have tried pg_upgrade from 9.3.3 to 9.4.0 and i have done with the
following procedure which will solve your problem.

Create .pgpass file in users home directory ~/.pgpass and add both server
with their respective user & password

Now Shut down 9.3.3 & 9.4.0 cluster

Now when ever you run pg_upgrade utility the present working directory
(pwd) should have write access of the current user e.g postgres

First just check if clusters are Clusters are compatible with using -c
options

Example:

/opt/PostgreSQL/9.4/bin/pg_upgrade -c -v -d /tmp/PostgreSQL/9.3.3/data/ -D
/tmp/PostgreSQL/9.4.0/data/ -b /opt/PostgreSQL/9.3.3/bin/ -B
/opt/PostgreSQL/9.4/bin/ -p 5888 -P 5999 -U postgres

If Result says Clusters are compatible then remove -c and start upgrading

Example:

/opt/PostgreSQL/9.4/bin/pg_upgrade -v -d /tmp/PostgreSQL/9.3.3/data/ -D
/tmp/PostgreSQL/9.4.0/data/ -b /opt/PostgreSQL/9.3.3/bin/ -B
/opt/PostgreSQL/9.4/bin/ -p 5888 -P 5999 -U postgres

If Result says Upgrade Complete then your upgrade is completed successfully.

I am also attaching the one file for reference.

Hope this will resolve your problem.
