## Pages

- [Changelog](changelog.md)

## Modules

- [Sourced.EventStore.Postgres](Sourced.EventStore.Postgres.md): A PostgreSQL implementation of `Sourced.EventStore` backed by your
application's Ecto repo.
- [Sourced.EventStore.Postgres.Checkpoint](Sourced.EventStore.Postgres.Checkpoint.md): Where a `Sourced.EventStore.Postgres.Subscriber` has got to: one row per
subscriber name in `sourced_checkpoints`, holding the last sequence the
subscriber committed and a fingerprint of the query it committed it over.
- [Sourced.EventStore.Postgres.Event](Sourced.EventStore.Postgres.Event.md): Ecto schema for the sourced events table, and every query the adapter runs
against it.
- [Sourced.EventStore.Postgres.Migrations](Sourced.EventStore.Postgres.Migrations.md): Migrations creating and upgrading the tables, triggers and functions the
event store reads and writes.
- [Sourced.EventStore.Postgres.Subscriber](Sourced.EventStore.Postgres.Subscriber.md): A subscriber that persists the last sequence that it processed.
- [Sourced.EventStore.Postgres.Subscription](Sourced.EventStore.Postgres.Subscription.md): A dynamically started GenServer for listening to appended events and dispatching to the caller.

- [Sourced.EventStore.Postgres.Tag](Sourced.EventStore.Postgres.Tag.md): Ecto schema for the side table queries match tags against, and the queries run
against it.
