Settings for using "PostgreSQL"

I downloaded "OrthancInstaller-Win64-1.2.0.exe" and installed it
I posted "PostgreSQL" according to "postgresql.json" but the log states "The PostgreSQL index is currently disabled, set" EnableIndex "to" true "in the" PostgreSQL "section of the configuration file of Orthanc "PostgreSQL" can not be used

The setting contents are
// List of paths to the custom Lua scripts that are to be loaded
// into this instance of Orthanc
"LuaScripts": [
],

"PostgreSQL": {
"EnableIndex": true,
"EnableStorage": true,
"Host": "localhost",
"Port": 5432,
"Database": "orthanc",
"Username": "orthanc",
"Password": "orthanc"

},

// List of paths to the plugins that are to be loaded into this
// instance of Orthanc (eg "./libPluginTest.so" for Linux, or
// "./PluginTest.dll" for Windows). These paths can refer refer to
// folders, in which case they will be scanned non-recursively to
// find shared libraries.
"Plugins": ["../ Plugins /"],

Please tell me the solution
