Click Next to continue and wait for the installation to complete.

PostGIS plugin installation

The PostGIS plug-in version needs to be consistent with the main version of PostgreSQL, and the PostGIS component must be installed; otherwise, geographic information-related data cannot be used.
Run the installation file as an administrator.

Select the installation path. If you want to install PostGIS to the PostgreSQL installation directory, you need to stop the postgresql service in advance, otherwise the installation file will fail to be written. Remember to start the postgresql service after the installation is complete.

If the backup file restoration dialog box cannot appear during the operation, check "File—Preference—Binary Path", find the configuration item of the current version, and change the path to the installation directory of the current version.

Uninstallation and cleaning of PostgreSQL and PostGIS

In the Windows environment, uninstall normally in "Control Panel - Programs and Features - Uninstall or change a program".
Enter "regedit" in the running window (Windows+R) to open the registry editor, find "HKEY_LOCAL_MACHINE\SOFTWARE", delete the registry entries related to PostGIS and PostgreSQL, and the cleaning is completed.
