AFAIK you can't do it through PgAdmin. It'd be rather nice if the service read its command line from an admin-writable-only text file in %PROGRAMFILES%\PostgreSQL\version rather than embedding the command line text directly in the service configuration. Unfortunately, it doesn't. This means you need to alter the Windows service directly. What you need to do is stop the PostgreSQL service, then move your data directory (by default in C:\Program Files\PostgreSQL\version\data where "version" is 8.4, 8.3, etc) to the new location, and finally modify the command line used by the service so Pg knows where to find its data directory. The service name is postgresql-version eg postgresql-8.4 . You can modify the service using sc.exe from the command line (for some bizarre reason, the services MMC snap-in services.msc doesn't support changing the service command line). If you're on Vista or above, you'll need to launch the command line with "run as administrator" or you won't have permission to do what you need to. On some older Windows versions you may need to install the Resource Kit to get sc.exe . Here's how to make the change. 1) get the service's current config: C:\Windows\system32>sc qc postgresql-8.4 [SC] QueryServiceConfig SUCCESS SERVICE_NAME: postgresql-8.4 TYPE : 10 WIN32_OWN_PROCESS START_TYPE : 2 AUTO_START ERROR_CONTROL : 1 NORMAL BINARY_PATH_NAME : C:/Program Files/PostgreSQL/8.4/bin/pg_ctl.exe runservice -N "postgresql-8.4" -D "C:/Program Files/PostgreSQL/8.4/data" -w LOAD_ORDER_GROUP : TAG : 0 DISPLAY_NAME : postgresql-8.4 - PostgreSQL Server 8.4 DEPENDENCIES : RPCSS SERVICE_START_NAME : .\postgres 2) stop the service: C:\Windows\system32>sc postgresql-8.4 stop SERVICE_NAME: postgresql-8.4 TYPE : 10 WIN32_OWN_PROCESS STATE : 3 STOP_PENDING (STOPPABLE, PAUSABLE, ACCEPTS_SHUTDOWN) WIN32_EXIT_CODE : 0 (0x0) SERVICE_EXIT_CODE : 0 (0x0) CHECKPOINT : 0x0 WAIT_HINT : 0x2710 3) Move the data directory using Windows Explorer. 4) modify the service configuration to tell Pg where the new data directory lives. Note the use of backslashes to escape innner quotes. Make sure to use exactly the same command line as is shown in BINARY_PATH_NAME above, except for changing the argument to -D to point to the new data directory. C:\Windows\system32>sc config postgresql-8.4 binPath= "\"C:/Program Files/PostgreSQL/8.4/bin/pg_ctl.exe\" runservice -N \"postgresql-8.4\" -D \"D:/NewPgDataDirPath\" -w" [SC] ChangeServiceConfig SUCCESS 5) Start the service C:\Windows\system32>sc start postgresql-8.4 SERVICE_NAME: postgresql-8.4 TYPE : 10 WIN32_OWN_PROCESS STATE : 2 START_PENDING (STOPPABLE, PAUSABLE, ACCEPTS_SHUTDOWN) WIN32_EXIT_CODE : 0 (0x0) SERVICE_EXIT_CODE : 0 (0x0) CHECKPOINT : 0x0 WAIT_HINT : 0xea60 PID : 3704 FLAGS : 6) Verify it's running C:\Windows\system32>sc query postgresql-8.4 SERVICE_NAME: postgresql-8.4 TYPE : 10 WIN32_OWN_PROCESS STATE : 4 RUNNING (STOPPABLE, PAUSABLE, ACCEPTS_SHUTDOWN) WIN32_EXIT_CODE : 0 (0x0) SERVICE_EXIT_CODE : 0 (0x0) CHECKPOINT : 0x0 WAIT_HINT : 0x0 -- Craig Ringer
