Entity Framework Core PostgreSQL Integration

See Entity Framework Core Integration document for the basics of the EF Core integration.

EntityFrameworkCore Project Update

• In Acme.BookStore.EntityFrameworkCore project replace package Volo.Abp.EntityFrameworkCore.SqlServer with Volo.Abp.EntityFrameworkCore.PostgreSql
• Update to use PostgreSQL in BookStoreEntityFrameworkCoreModule. Example:

[DependsOn(
        //code omitted for brevity
		
		/* This was updated from AbpEntityFrameworkCoreSqlServerModule */
        typeof(AbpEntityFrameworkCorePostgreSqlModule),
		/* This was updated from AbpEntityFrameworkCoreSqlServerModule */
        
		//code omitted for brevity
        )]
public class Acme.BookStore.EntityFrameworkCoreModule : AbpModule
    {
        public override void ConfigureServices(ServiceConfigurationContext context)
        {
            context.Services.AddAbpDbContext<BookStoreDbContext>(options =>
            {
                options.AddDefaultRepositories(includeAllEntities: true);
            });

            Configure<AbpDbContextOptions>(options =>
            {
                /* This was updated */
                options.UsePostgreSql();
				/* This was updated */
            });
        }
    }
