Bruce,
To query for Postgresql services on Windows use:
sc query type= service | find "postgresql"
On my machine this yields:
SERVICE_NAME: postgresql-9.0
DISPLAY_NAME: postgresql-9.0 - PostgreSQL Server 9.0
NB the space after type= is very important, don't ask me why...
I prefer to use 'sc start <servicename>' and 'sc stop <servicename>',
then you can use one tool for everything.
The following shows these commands (and the query command) in action.
C:\Documents and Settings\Administrator>sc stop postgresql-9.0
SERVICE_NAME: postgresql-9.0 TYPE : 10 WIN32_OWN_PROCESS STATE : 3
STOP_PENDING (STOPPABLE, PAUSABLE, ACCEPTS_SHUTDOWN) WIN32_EXIT_CODE : 0 (0x0)
SERVICE_EXIT_CODE : 0 (0x0) CHECKPOINT : 0x2 WAIT_HINT : 0x2710
C:\Documents and Settings\Administrator>sc start postgresql-9.0
SERVICE_NAME: postgresql-9.0 TYPE : 10 WIN32_OWN_PROCESS STATE : 2
START_PENDING (NOT_STOPPABLE, NOT_PAUSABLE, IGNORES_SHUTDOWN))
WIN32_EXIT_CODE : 0 (0x0) SERVICE_EXIT_CODE : 0 (0x0) CHECKPOINT : 0x0 WAIT_HINT
: 0x7d0 PID : 3732 FLAGS :
C:\Documents and Settings\Administrator>sc query postgresql-9.0
SERVICE_NAME: postgresql-9.0 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
Hope this isn't too much info and answers all your questions :-)
Regards,
Colin
