Postgres SaaS documentation model

Postgres SaaS documentation is maintained as versioned product documentation. The current stable docs live at the canonical /guides path, while historical product docs live under explicit /versions/[version]/guides paths.

Version semantics#

Stable: the current production guidance for new SaaS deployments.
Previous: retained for teams still operating an older product baseline.
Unversioned support: troubleshooting and operational support articles stay unversioned when the answer should always reflect the current support policy.

Content organization#

Current product guides belong under content/guides/postgres-saas. Historical guides belong under content/versions/[version]/guides/postgres-saas.

This keeps product behavior version-aware without copying short-lived support articles into every version archive.
