How do you uninstall the previous version of PostgreSQL?
We have upgraded our MagicInfo build to NA-MICS-20.1010.7 to move away from Postgresql 9.3 and onto 9.6 to address some security vulnerabilities. I then uninstalled PostgreSQL 9.3 but was unable to login into the control panel even though the web interface loads as normal. When trying to log in it says the username and password are incorrect despite the credentials not being changed.
Any help would be great, TIA!
