I've got all PT programs running as administrator on Vista. I did the properties > advanced > tick run as administrator. If I need to run postgres as an administrator then I don't know how to do that as it is running as a service. This password reappearing when trying to restore does not look like an isolated case. I found that it happened to someone else in this thread.
viewtopic.php?f=32&t=11192&p=52491See the second to last post of the thread "Ok, I changed the md5 to trust and saved. Click the restore dbase in PTO, and again it asks for a password (which it shouldn't at this stage...)" This never got followed up because as he says he uninstalled it all but it looks like exactly the problem I have. I suspect it is an issue with PTO and postgres 8.3.3 but I have no idea how to fix it.
