Subject: BUG #17096: Cannot reinstall after uninstalling PostgreSQL on Windows 10 Pro for Workstations
Date: Fri, 09 Jul 2021 05:34:50 +0000
Message-ID: <17096-48711ba20f7ac228@postgresql.org> (raw)
The following bug has been logged on the website:
Bug reference: 17096
Logged by: Yuetsuro Kobayashi

PostgreSQL version: 13.3
Operating system: Windows10 Pro for Workstations
Description:
When I installed PostgreSQL13 after uninstalling PostgreSQL12 on a "Windows
10 Pro for Workstation/OS" machine, "Failed to initialize data directory"
and "Parse error" occurred.
This issue has caused the symptom many times in older versions and I believe
it also has issues in the current latest version.
When the issue occurs, the only solution is a silly solution called an OS
clean install.
Is this the right method ?
I manually deleted the data directory and the installation directory
(PostgreSQL\13) after the uninstall operation on Windows, but the
installation fails. I also tried Registry Clean, but it still fails to
install.
The issue is that depending on the OS type, the installation succeeds or
fails during a reinstall after uninstalling.
There are two machine information known at this time.
・ Windows10 Pro for Workstations → Reinstallation fails after
uninstalling
CPU : Intel(R) Xeon(R) Gold 5222 CPU@3.80GHz
RAM : 192GB
・ Windows10 Pro → After uninstalling, reinstallation succeeds
CPU : Intel(R) Core(TM) i9-9820X CPU@3.3GHz
RAM : 64GB
