PostgreSQL Global Development Group
(https://postgresql.org) 📸 Data Snapshot: June 11, 2026Count trust words (review, testimonial, rating, verified) against real outbound proof links (Google, Trustpilot, Clutch, G2, Yelp). Lots of trust language with zero verification links is trust theatre. Unlinked logo galleries count against it.
The site triggers a minor trust theatre penalty because the homepage displays a review_count of 2 with a proof_links_count of 0, indicating that community testimonials from entities like Zalando and SippySoft are not linked to external verification sources in the metadata. However, the presence of specific names and companies mitigates the impact of this forensic flag.
Proof density is extremely high. The site provides a complete versioning history dating back to version 6.3 in 1998, a live download matrix for 10+ operating systems, and a public bug reporting form. Verifiable evidence (commits, contributor counts, release dates) outweighs vague assertions by a factor of roughly 10:1.
Trust & Proof is read by weighing trust language against real verification. Below is the page-by-page tally of review mentions and external proof links, then the schema markup that may (or may not) declare verifiable ratings and identity proof.
