How to use local storage instead of volatile memory?

How to change the appsettings.Development.json to use persistent storage instead of volatile memory ?

and how to rebuild the kernel with added Postgres connection ? there is no public available package to run below snippet.

var postgresConfig = new PostgresConfig();

new ConfigurationBuilder()
.AddJsonFile("appsettings.json")
.AddJsonFile("appsettings.Development.json", optional: true)
.Build()
.BindSection("KernelMemory:Services:Postgres", postgresConfig);

var memory = new KernelMemoryBuilder()
.WithPostgres(postgresConfig)
.WithAzureOpenAITextGeneration(azureOpenAIConfig)
.WithAzureOpenAITextEmbeddingGeneration(azureOpenAIConfig)
.Build();

One more help. when used "MemoryDbTypes": ["Postgres"] ...
I could see all vectorDB table created in the database,
but GET indexes endpoint return empty list.
and POST ask has no result.

is there anything need to be added to these two API requests to use Postgres instead of SimpleVectorDb ?

i found the below settings fix the endpoint issues :).
"Retrieval": {
"MemoryDbType": "Postgres",

you may want to try dotnet run setup to create an initial setting file. The wizard might help understanding how it all comes together
