At the end of this article:

https://learn.microsoft.com/en-us/dotnet/aspire/database/postgresql-component?tabs=dotnet-cli

We should link on to a new article which describes how to deploy a .NET Aspire application with a Postgres database resource to Azure. We have a new API for this that generates Bicep that is used by AZD.

builder.AddPostgres("pgsql").PublishAsAzurePostgresFlexibleServer().AddDatabase(db);

Hey @mitchdenny - is that code accurate?

I noticed that the db parameter in the AddDatabase call isn't a string, I'm assuming that's a typo.

Should that instead be:

builder.AddPostgres("pgsql")
       .PublishAsAzurePostgresFlexibleServer()
-      .AddDatabase(db);
+      .AddDatabase("db");

Yeah its a typo. Thanks!
