## v1.0.0 — Stable Release

**Goal:** First officially supported release. Semantic versioning locks in.
API, catalog schema, and GUC names are considered stable. Focus is
distribution and trust: getting pg_trickle onto package registries, shipping
signed artifacts and SBOMs with provenance, and proving PostgreSQL 19
forward-compatibility.

### PostgreSQL 19 Forward-Compatibility (A3)

> **In plain terms:** When PostgreSQL 19 beta stabilises and pgrx 0.18.x
> ships with PG 19 support, this milestone bumps the pgrx dependency,
> audits every internal `pg_sys::*` API call for breaking changes, adds
> conditional compilation gates, and validates the WAL decoder against any
> pgoutput format changes introduced in PG 19. Moved here from the
> earlier v0.26.0 milestone because PG 19 beta availability is uncertain.

| Item | Description | Effort | Ref |
|------|-------------|--------|-----|
| A3-1 | pgrx version bump to 0.18.x (PG 19 support) + `cargo pgrx init --pg19` | 2–4h | [PLAN_PG19_COMPAT.md](plans/infra/PLAN_PG19_COMPAT.md) §2 |
| A3-2 | `pg_sys::*` API audit: heap access, catalog structs, WAL decoder `LogicalDecodingContext` | 8–16h | [PLAN_PG19_COMPAT.md](plans/infra/PLAN_PG19_COMPAT.md) §3 |
| A3-3 | Conditional compilation (`#[cfg(feature = "pg19")]`) for changed APIs | 4–8h | [PLAN_PG19_COMPAT.md](plans/infra/PLAN_PG19_COMPAT.md) §4 |
| A3-4 | CI matrix expansion for PG 19 + full E2E suite run | 4–8h | [PLAN_PG19_COMPAT.md](plans/infra/PLAN_PG19_COMPAT.md) |

> **A3 subtotal: ~18–36 hours**

### Release engineering

> **In plain terms:** The 1.0 release is the official "we stand behind this
> API" declaration — from this point on the function names, catalog schema,
> and configuration settings won't change without a major version bump. The
> practical work is getting pg_trickle onto standard package registries
> (PGXN, apt, rpm) so it can be installed with the same commands as any
> other PostgreSQL extension, and hardening the CloudNativePG integration
> for Kubernetes deployments.

| Item | Description | Effort | Ref |
|------|-------------|--------|-----|
| R1 | Semantic versioning policy + compatibility guarantees | 2–3h | [PLAN_VERSIONING.md](plans/infra/PLAN_VERSIONING.md) |
| R2 | apt / rpm packaging (Debian/Ubuntu `.deb` + RHEL `.rpm` via PGDG) | 8–12h | [PLAN_PACKAGING.md](plans/infra/PLAN_PACKAGING.md) |
| R2b | PGXN `release_status` → `"stable"` (flip one field; PGXN testing release ships in v0.7.0) | 30min | [PLAN_PACKAGING.md](plans/infra/PLAN_PACKAGING.md) |
| R3 | ~~Docker Hub official image~~ → CNPG extension image | ✅ Done | [PLAN_CLOUDNATIVEPG.md](plans/ecosystem/PLAN_CLOUDNATIVEPG.md) |
| R4 | ~~CNPG operator hardening (K8s 1.33+ native ImageVolume)~~ ➡️ Pulled to v0.15.0 | 4–6h | [PLAN_CLOUDNATIVEPG.md](plans/ecosystem/PLAN_CLOUDNATIVEPG.md) |
| R5 | **Docker Hub official image.** Publish `pgtrickle/pg_trickle:1.0.0-pg18` and `:latest` to Docker Hub. Sync Dockerfile.hub version tag with release. Automate via GitHub Actions release workflow. | 2–4h | — |
| R6 | **Version sync automation.** Ensure `just check-version-sync` covers all version references (Cargo.toml, extension control files, Dockerfile.hub, dbt_project.yml, CNPG manifests). Add to CI as a blocking check. | 2–3h | — |
| SAST-SEMGREP | **Elevate Semgrep to blocking in CI.** CodeQL and cargo-deny already block; Semgrep is advisory-only. Flip to blocking for consistent safety gating. Before flipping, verify zero findings across all current rules. | 1–2h | [PLAN_SAST.md](plans/testing/PLAN_SAST.md) |
| OTL-1 | **OpenTelemetry tracing spans.** Add `pgtrickle.refresh`, `pgtrickle.cdc_capture`, and `pgtrickle.snapshot` spans via the OTel SDK so every pg_trickle operation is visible to OTel collectors. Minimum viable: trace_id propagation through the refresh pipeline; attribute set = `stream_table`, `refresh_mode`, `rows_processed`. | 4–8h | [PLAN_OVERALL_ASSESSMENT_3.md](plans/PLAN_OVERALL_ASSESSMENT_3.md) §9.6 |
| SIGN-1 | **Cosign-sign GHCR release images.** Add `cosign sign` step to the GitHub Actions release workflow for `grove/pg-trickle`, `grove/pgtrickle-relay`, and `pg_trickle-ext` GHCR images. Attach Rekor transparency log entry. Document `cosign verify` command in `SECURITY.md`. | 2–4h | [PLAN_OVERALL_ASSESSMENT_3.md](plans/PLAN_OVERALL_ASSESSMENT_3.md) §9.11 |
| SIGN-2 | **Publish SBOMs for extension and release artifacts.** Generate CycloneDX or SPDX SBOMs for the extension tarball, relay binary, and release images; attach them to GitHub releases and document how operators verify them. | 2–4h | [PLAN_OVERALL_ASSESSMENT_8.md](plans/PLAN_OVERALL_ASSESSMENT_8.md) §10 |
| SIGN-3 | **Attach provenance attestations to release workflows.** Emit SLSA-style provenance or equivalent signed attestations for published binaries and images so operators can verify how each artifact was built. | 2–4h | [PLAN_OVERALL_ASSESSMENT_8.md](plans/PLAN_OVERALL_ASSESSMENT_8.md) §10 |
| MDB-1 | **Promote G17-MDB multi-database soak test to `ci.yml`.** The `stability-tests.yml` G17-MDB job runs multi-database scenarios in isolation. Move it to `ci.yml` under the "Push to main" trigger alongside the existing soak test. Gate it on a 30-min wall-clock budget for PR CI; use the full 2-hour run on schedule. | 2–3h | [PLAN_OVERALL_ASSESSMENT_3.md](plans/PLAN_OVERALL_ASSESSMENT_3.md) §9.10 |

> **v1.0.0 total: ~46–86 hours** (incl. PG 19 compat ~18–36h + release engineering ~18–30h + OTel/signing/SBOM/provenance/MDB ~12–20h)
