Services Still Showing Up
Even after uninstalling PostgreSQL 16, you might still see related services in the list. This is due to the fact that some services are registered in the Windows Registry and do not get removed during the uninstallation process.
Solutions
To remove the unwanted services, you can manually edit the Windows Registry or use third-party tools like CCleaner or Registry Cleaner.
Manual Registry Editing
Warning: Editing the Windows Registry can cause serious problems if not done correctly. Proceed with caution and make a backup of your registry before making any changes.
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services
<# Delete PostgreSQL services #>
"PG_X11"="dword:00000004"
"PGPool2"="dword:00000004"
"PostgreSQL-x64-11"="dword:00000004"
"PostgreSQL-x64-12"="dword:00000004"
"PostgreSQL-x64-15"="dword:00000004"
"PostgreSQL-x64-16"="dword:00000004"
"PostgreSQL-x64-17"="dword:00000004"
