Then do the command you wrote above (or some variation of it) to install postmaster new. ____________________________________________________________ COMMENTS Something to note, however. Not sure when you say you 'faulty' if you mean that you typed the initial $ cygrunsrv command incorrectly (e.g., with incorrect switches, etc.), or simply that you had issues with PostgreSQL due to something like the NT username/password that you are running postmaster under. Note if you change the NT user and/or password that you run postmaster under, simply bring up your Service Manager (I tend to right-click on 'My Computer' and choose 'Manage' from the popup menu, but there's about 1/2 dozen ways to get there), double-click on the postmaster service to bring up its properties, cick the 'Log On' tab, and change the username/password as needed. In most cases, you do NOT need to remove and reinstall the NT service. Note that Windows NT services are basically just Registry entries. That is, once you've done the cygrunsrv command you listed above, Windows knows that when you start/stop/restart the NT service 'postmaster', it needs to go to a specific directory and fire up/shutdown/kick a specific executable. Kinda like a BATch file. In Unix-speak, they're kinda like your initscripts. For example, just because you update your installation of PostgreSQL on Linux, you don't need to remove/reinsert any commands you have in your initscripts, right? (assuming paths remain the same, of course :-) ) Well, same deal here. Once you've done the cygrunsrv command to 'hook in' PostgreSQL as an NT service, you should not need to re-do this command in the future. The ONLY time you may need to do so is if you need to change the parameters you listed when you ran cygrunsrv (e.g., you want to change the path to the data store listed after -D).
