Create a table for use by multiple tenants

Create.Table("widgets")
    .WithColumn("id").AsGuid().NotNullable().PrimaryKey()
    .WithColumn("tenant").AsString().NotNullable() // This column indicates which tenant a row belongs to
    .WithColumn("registration").AsString().Nullable().Unique()
    .WithColumn("data").AsCustom("jsonb").NotNullable();

All rows can be accessed

// Create a separate account for administrators to login with
Execute.Sql($"CREATE USER {Username} LOGIN PASSWORD '{Password}';");

// Give this administrators account access to the table 
Execute.Sql($"GRANT {Permissions} ON {Table} TO {Username};");

// Define the policy that will be applied
Execute.Sql($"CREATE POLICY {Policy} ON {Table} FOR ALL TO {Username} USING (true);");

Only those rows where the tenant identifier stored in the app.tenant context matches the tenant column can be accessed

// Create a separate account for tenants to login with
Execute.Sql($"CREATE USER {Username} LOGIN PASSWORD '{Password}';");

// Give this tenant account access to the table 
Execute.Sql($"GRANT {Permissions} ON {Table} TO {Username};");

// Define the policy that will be applied
Execute.Sql($"CREATE POLICY {Policy} ON {Table} FOR ALL TO {Username} USING ({Column} = current_setting('app.tenant')::VARCHAR);");
