Excalibur.Outbox.Postgres

Postgres implementation of the transactional outbox pattern for reliable message delivery.

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.

Schema

The store does not create its tables at runtime. Provision them before the first message is staged, by running the script shipped inside this package under scripts/:

scripts/001_CreateOutboxSchema.sql

Run it against your target database:

psql -h host -U user -d database -f 001_CreateOutboxSchema.sql

It creates three tables, using the default names:

Table	Purpose
`outbox`	Staged messages awaiting delivery
`outbox_dead_letters`	Messages that exhausted their retries
`outbox_fence`	Durable leadership high-water mark, kept out of the message table so draining cannot lower it

If you override SchemaName, OutboxTableName, DeadLetterTableName, or FenceTableName, rename the corresponding objects in the script to match.

Every statement is guarded with IF NOT EXISTS, so the script is safe to re-run.

Postgres specifics

All timestamp columns are TIMESTAMPTZ. A column created WITHOUT TIME ZONE is shifted by the session timezone on reload, so a scheduled message would become due at the wrong instant.
tenant_id is NOT NULL DEFAULT '__untenanted__'. An untenanted message stores the reserved sentinel, not NULL, so there is exactly one way to say a message has no tenant and a scoped predicate always compares a value against a value. The staging path binds the term explicitly, so the default is a backstop for hand-written INSERTs.
A database created while tenant_id was nullable is converged by 002_MakeOutboxTenantTotal.sql, which backfills NULL (and blank) to the sentinel before applying the constraint. Run it with the processor stopped, and deploy this package version first — the older package binds a raw null tenant and would fail the new constraint.
outbox_fence.scope_key must keep its primary key — the fenced claim and fenced delete upsert with ON CONFLICT (scope_key), which requires a matching unique constraint.
