Excalibur.EventSourcing.Postgres

Postgres implementations for Excalibur event sourcing, including event store, snapshot store, and outbox store. Uses Npgsql and Dapper for high-performance data access.

Part Of

This package is included in the following metapackages:

Metapackage	Tier	What It Adds
`Excalibur.Dispatch.Postgres`	Starter	+ Dispatch core + Outbox + Hosting
`Excalibur.Postgres`	Complete	+ Inbox + Saga + Leader Election + Audit + Compliance + Data

Tip: Install Excalibur.Postgres for a production-ready PostgreSQL stack with a single package reference.

Installation

dotnet add package Excalibur.EventSourcing.Postgres

Quick Start

using Microsoft.Extensions.DependencyInjection;

services.AddExcalibur(excalibur => excalibur.AddEventSourcing(es =>
    es.UsePostgres(pg => pg.DataSource(dataSource))));

Features

Event Store -- Postgres-backed IEventStore with optimistic concurrency
Snapshot Store -- Postgres-backed ISnapshotStore for aggregate state snapshots
Outbox Store -- Postgres-backed outbox for reliable message publishing
AOT Compatible -- Full Native AOT and IL trimming support
Health Checks -- Integrated Postgres health check registration
Auto-Migration -- Optional PostgresMigrationHostedService for schema setup

Configuration

services.AddExcalibur(excalibur => excalibur.AddEventSourcing(es =>
    es.UsePostgres(pg => pg
        .DataSource(dataSource)
        .EventStoreSchema("events")
        .EventStoreTable("event_store"))));

Documentation

See the Postgres data provider guide for detailed configuration and usage.

License

This package is part of the Excalibur framework. See LICENSE for license details.

Schema

This package never creates its tables at runtime. Provision them before the first append — PostgresMigrator is not a provisioning path, it runs migrations from an assembly you supply.

The canonical DDL ships in the package:

script	creates
`scripts/001_CreateSnapshotSchema.sql`	`public.event_store_snapshots`
`scripts/004_CreateEventStoreSchema.sql`	`public.events`

Defaults: schema public, tables events and event_store_snapshots, all configurable via PostgresEventSourcingOptions. Without the event-store table the first append fails with 42P01: relation "events" does not exist.

Both scripts are re-runnable and only ever create missing objects; neither alters an existing table. scripts/002_… and scripts/003_… are migrations for databases provisioned by earlier versions — read their headers before running them, as one is order-dependent with the package release that introduced it.
