while preserving the existing explanation that successful periodic re-checks are
silent and the warning appears once at boot.
- Around line 365-373: Update the renewal verification guidance to wait until
the mounted certificate file reflects the Secret change before declaring
success, then verify its new fingerprint; alternatively direct readers to the

Make the local-path storage prerequisite explicit.
These four manifests hard-code storageClassName: local-path, but Before You Begin does not require that StorageClass. If it is absent, PVC provisioning remains pending and the guide cannot reach Ready or license verification. Add a prerequisite and availability check, or use a documented cluster-available/default StorageClass. KubeDB documents that the named StorageClass must be available in the cluster. (kubedb.com)

Patch the configured Secret key during renewal.
If spec.license.secretRef.key is not license.pem, this command writes the renewed certificate to the wrong key. The patch succeeds, but KubeDB continues to mount the configured key and does not use the renewal. Patch the actual secretRef.key, using license.pem only when the key is omitted.

Verify certificate identity before applying a renewal.
This command checks only the certificate dates. It does not confirm the license CN, product O, issuer, or fingerprint. Include the identity fields or fingerprint so a certificate for a different license cannot pass this pre-check.

…psCode PR #1052 documents the new spec.license and spec.distribution fields as reference material. This adds the task-oriented counterpart: a walkthrough that takes a user from "I have a license certificate" to a running, verified licensed database, plus the day-2 concerns that only show up once one is running. Every command and every quoted output in the guide was executed against a live cluster running the licensed 16.9-appscode builds, and the guide was then replayed from a clean namespace to confirm it works as written. The three findings that most shaped the content, all of them observed rather than assumed: - A successful periodic license re-check logs nothing. Only failures are logged, so there is no positive signal to wait for after an in-place renewal, and the 30-day expiry warning is emitted at startup rather than daily. The guide therefore points at days_remaining for alerting. - A license that fails re-verification triggers a fast shutdown, and it does not self-heal. Restoring a valid certificate is necessary but not sufficient; the pod has to be deleted. - That shutdown leaves the pod reporting 1/1 Running with a restart count of 0, because the container entrypoint outlives the server. Only the Postgres object's NotReady phase reveals it. This is called out as the most confusing failure in the guide. Also documents which bundled extensions in the -ext images work as-is and which need shared_preload_libraries, the container scoping of the license mount, and why the license is absent from backups of PGDATA.

Reworks the guide to read as documentation for a supported commercial product rather than a catalogue of ways it can fail. The technical content a customer needs is unchanged, and every command still matches verified output. - Drop the claim that the enterprise branding is "cosmetic". It described version compatibility, which is a reason to adopt the product, so it now says that plainly instead. - Remove the pod-internals section: the PGLICENSE variable, the mount path listing and its symlink aside, and the container-by-container breakdown of which one holds the license. None of it is actionable for a user, and the two facts that are -- the license sits outside PGDATA, so it stays out of backups and a restored database needs its own -- are kept. - Condense renewal to the part that matters: it is an in-place, online operation. Recovery from a rejected certificate is now four lines rather than a section. - Fold the three separate certificate-rejection headings into one table, keeping the exact log strings that make them searchable, and drop the incidental initdb data-directory message. - Reframe the two-licenses note as information rather than a warning. Net effect: 196 lines removed, 90 added. Signed-off-by: souravbiswassanto <saurov@appscode.com>

Adds a task-oriented walkthrough for running the licensed Postgres Enterprise by AppsCode distribution, complementing #1052 (which adds the
spec.license/spec.distributionreference material to the concepts pages). No overlap — #1052 describes the fields, this describes the job.New files:
docs/guides/postgres/enterprise/postgres-enterprise.md— the guidedocs/guides/postgres/enterprise/_index.md— section index (weight 125, after Private Registry)docs/examples/postgres/enterprise/{postgres-enterprise,postgres-enterprise-ha}.yamlREADME.mduser-guide listShape of the guide
Get a license → find the licensed versions in the catalog → store it in a Secret → deploy → confirm it was accepted → connect and use it. Then the day-2 material: HA, the extension-enabled images, renewal, and a short troubleshooting section organised by where the problem surfaces (webhook / pod events / server log).
Renewal is covered as a first-class operation rather than an afterthought: the server re-reads the certificate periodically, so replacing the Secret is picked up online with no restart, no downtime and no ops request.
Verification
Every command and every quoted output was executed against a live cluster running the licensed
16.9-appscodebuilds, then the guide was replayed from a clean namespace to confirm it works exactly as written. Nothing in it is illustrative-only.Confirmed along the way:
spec.license.secretRef.keyis genuinely optional — the mutating webhook defaults it tolicense.pemPGDATA, so it stays out of backups and a restored database needs its ownspec.license-extimages work as-is (pgvector,PostGIS,pg_repack) and which needshared_preload_libraries(pg_cron,pgaudit)Two practical points the testing surfaced
Both are in the guide because a customer would otherwise have to discover them:
Alert on
days_remaining, not on the log. The 30-day expiry warning is written at startup, so a long-running database logs it once rather than repeatedly.appscode_license_info()exposes the same number and can be scraped on a schedule.During a license stop, check
kubectl get pg, not the pod. ThePostgresobject correctly reportsNotReady, while the pod continues to report1/1 Running. The guide says which one to trust, and the recovery is onekubectl delete podwith data intact.Note
The guide documents
16.9-appscode*versions, whose catalog entries are still in kubedb/installer#2425. This shouldn't merge ahead of that one, or it documents versions users cannot yet see.
