Re: Uninstalling PostgreSQL

Hi Barry,

First, check that all your cygwin services are stopped, specifically the cygipc service. See your services control panel. However, you can't remove them there, you need to either hack the registry for that or the ipc-daemon2.exe with the proper commandline-options.

regards,

Subject: [CYGWIN] Uninstalling PostgreSQL

I want to uninstall PostgreSQL and all related packages. I don't even need Cygwin, so I've been trying to delete the cygwin directory, since there is no cygwin uninstaller.

The first problem was an "access is denied" message for cygcrypt-0.dll. Then I deleted the postgres user's account and did some stuff with permissions and various other things, and I was able to delete cygcrypt-0.dll, but then I had the same problem with cygcygipc-2.dll, and I don't want to figure out exactly what I did to delete cygcrypt-0.dll and apply it to each problem-file individually. I want an easy, directory-wide solution. But I have a feeling I'll need cygcrypt-0.dll back to fix the next problem.

I tried using chmod and chown on the cygwin directory at the Windows command prompt (the cygwin console no longer exists), but it seemed to fail. Maybe I used the wrong commands. I didn't get any error, but I still wasn't able to delete the cygwin directory, and the properties still said "read only." When I unchecked "read only" and clicked "apply" and "ok", I got an "Error applying attributes" pop-up about C:\cygwin\tmp\cygipc2_2. I heard that indicates encryption, but the "encrypt contents to secure data" box for that file is not checked. This is why I have a feeling I need cygcrypt-0.dll back.

I also tried deleting as many files as I could, in small groups, starting with the bin directory, from the top of the list down. The show stopper that time was "The file 'bzless' is a system file. If you remove it, you're computer or one of your programs may no longer work correctly. I think I got a similar warning for cygcrypt-0.dll, but I wasn't as brave this time and didn't try to remove it.

Any suggestions for removing my cygwin directory and all of its contents in a safe way, along with anything PostgreSQL might have done, would be appreciated.

Thanks,
Barry
