pg_ctl only checks the status of an instance running on the local machine. To check on a remote linux box from windows using pg_ctl, you'd have to run pg_ctl on the linux box, probably over SSH (look for Putty for an SSH client for Windows). An easier option might be to run a psql command on the remote database. Just run something like "SELECT 1" and check you actually get a 1 back, and not a connection error. > We'd be using FME to push data from other databases into PostgreSQL, however > before running our FME scripts we'd want to check the DB is up and running. > If the DB is running, then run the FME scripts, if not...don't run the FME > scripts.
