The model for context 'PostgresContext' has pending changes.

Hi,

When we moved to .Net 9 and update packages we got this issue:

Unhandled exception. System.AggregateException: One or more errors occurred. (An error was generated for warning 'Microsoft.EntityFrameworkCore.Migrations.PendingModelChangesWarning': The model for context 'PostgresContext' has pending changes. Add a new migration before updating the database. See https://aka.ms/efcore-docs-pending-changes. This exception can be suppressed or logged by passing event ID 'RelationalEventId.PendingModelChangesWarning' to the 'ConfigureWarnings' method in 'DbContext.OnConfiguring' or 'AddDbContext'.)

.AddWorkflow(options => options.UsePostgreSQL(connectionString: appSettings.ConnectionStrings.PostgresWorkflowDb, true, true))

`

public static void RegisterWorkflows(this IApplicationBuilder app, params Assembly[] assemblies)
{
    var host = app.ApplicationServices.GetService<IWorkflowHost>();
    
    host.RegisterWorkflow<ShopServiceJobWorkflow, ShopServiceJobWorkflowContext>();
    host.RegisterWorkflow<CustomerServiceRequestWorkflow, CustomerServiceRequestWorkflowContext>();

    host.Start();
}

`

WorkflowCore 3.13.0
WorkflowCore.Persistence.PostgreSQL 3.13.0
Microsoft.EntityFrameworkCore 9.0.1

P.S: Creating a new migration didn't solve this issue
