pg_upgrade could not connect to server

hi all,

I'm trying to follow the pg_upgrade docs from
http://www.postgresql.org/docs/9.4/static/pgupgrade.html

I'm on Windows 64bit, and experience a few issues:

1) I do not have a "postgres" user account. the services are run by the
Network Service account.

2) minor: the service names include "-x64" suffix which is really
unnecessary and makes the docs stray from the implementation.

3) the main problem, possibly related to issue 1 above, is the following
error message:

Performing Consistency Checks
-----------------------------
Checking cluster versions ok

*failure*
Consult the last few lines of "pg_upgrade_server_start.log" or "pg_upgrade_server.log" for
the probable cause of the failure.

connection to database failed: could not connect to server: Connection refused (0x0000274D/10061)
Is the server running on host "localhost" (::1) and accepting
TCP/IP connections on port 50432?
could not connect to server: Connection refused (0x0000274D/10061)
Is the server running on host "localhost" (127.0.0.1) and accepting
TCP/IP connections on port 50432?

could not connect to old postmaster started with the command:
"C:\Program Files\PostgreSQL\9.3\bin/pg_ctl" -w -l "pg_upgrade_server.log" -D "E:\PGSQLData" -o "-p 50432 -b " start

any help would be appreciated.

thanks!
