pgsql: Backpatch pg_upgrade fixes to 9.0: In pg_upgrade, prevent psql

Log Message:
-----------
Backpatch pg_upgrade fixes to 9.0:

In pg_upgrade, prevent psql AUTOCOMMIT=off by not loading .psqlrc.

In pg_upgrade, report /bin directory checks independent of /data checks.

Remove incorrect email address for pg_upgrade bug reports.

On Win32, pg_upgrade cannot sent any server log output to the log file
because of file access limitations on that platform.
