Re: BUG #4581: Difficult uninstall

Thanks Dave for your quick reply.

So, as I understand it, the registry entries are left to simplify e.g. at
reinstallation enabling skip of some steps in the wizard.
The reason I was asking, is that I tried an application I have made on a
number of persons, and that some of them forgot the password they set on
the internal user (the DBO). The only way that I could come up with, was to
reinstall PostgreSQL.

Is there an other way?

Yes.

\PostgreSQL.

They are still remaining because they are your data. You wouldn't want
them to be removed when upgrading I assume?

It could, but we have no way of knowing if you're using that user
account for something else - for example, a different version (or
distribution) of PostgreSQL. Running two in parallel is not uncommon
when performing a major upgrade. Removing the user account could
easily break other things quite horribly.

Some keys are retained to tell any future (re)installation or minor
upgrade where to find the data that was left behind.

Your keyboard seems to be broken.
