grate.postgresql 1.7.4

grate

grate is a SQL scripts migration runner, using plain, old SQL for migrations. No meta-language, no code, no config, no EF migrations. It gives you full flexibility, and full control of your migrations, and lets you use all the fancy features of you particular database system. You are not constrained to any lowest common feature set of all supported databases.

grate.postgresql

This is the PostgreSQL provider for grate. It is used to deploy SQL scripts programmatically to a PostgreSQL database. For command line usage, please see the grate (dotnet tool) package.

Minimal code example

The only required argument to pass to grate is a connection string to tell it where to find your database. It will deploy to that database, looking for sql scripts in the current directory.

[Fact]
public async Task Run_migration_agains_target_db()
{
    var serviceCollection = new ServiceCollection();
    serviceCollection.AddLogging();
    serviceCollection.AddGrate(builder =>
    {
        builder
            .WithSqlFilesDirectory("/db")
            .WithConnectionString("postgresql connection string here")
    })
    .UsePostgreSql(); // Important!, you need to specify the database type to use.
    var serviceProvider = serviceCollection.BuildServiceProvider();
    var grateMigrator = serviceProvider.GetRequiredService<IGrateMigrator>();
    await grateMigrator.Migrate();
}

for more configuration options, see the documentation.

grate supports the following DMBS's

Database	NuGet package
Microsoft SQL server (sqlserver)
PostgreSQL (postgresql)
MariaDB/MySQL (mariadb)
Sqlite (sqlite)
Oracle (oracle)

grate.core

This is the core package, which does nothing by itself. It is mostly useful for writing extensions to grate, or for writing your own database provider. Please feel free to create your own database provider, and submit it a pull request, if you need support for a database that is not supported yet.
