使用pg_upgrade工具为PostgreSQL进行版本升级

pg_upgrade -b oldbindir -B newbindir -d olddatadir -D newdatadir [option...]

RUNAS /USER:postgres "CMD.EXE"
SET PATH=%PATH%;C:\Program Files\PostgreSQL\9.2\bin;

set Path = %Path%;C:\Program Files\PostgreSQL\9.2\bin
cd /d "C:\Program Files\PostgreSQL\9.2\bin"

There seems to be a postmaster servicing the old cluster.
Please shutdown that postmaster and try again.

If pg_upgrade fails after this point, you must re-initdb the
new cluster before continuing.

Upgrade Complete
----------------
Optimizer statistics are not transferred by pg_upgrade so,
once you start the new server, consider running:
    analyze_new_cluster.bat

Running this script will delete the old cluster's data files:
    delete_old_cluster.bat

cd /d C:\Program Files\PostgreSQL\9.2\bin
analyze_new_cluster.bat
