What the models said for it

Verbatim evidence the judge attached to positive labels.

No positive label carried a quote.

And against it

Verbatim evidence attached to negative labels. A warning on a product with few labels is a warning; on a product with many, it is one voice among them.

“Choose Postgres instead only if your data is genuinely small... Otherwise, BigQuery gives you considerably more room to grow.” GPT-5.6 Sol · Warehouse & ETL · budget prompt · soft negative

“Postgres is also mentioned as a viable choice for limited budgets, but it is usually better as a simpler operational database” Perplexity Sonar Pro · Warehouse & ETL · budget prompt · soft negative

“PostgreSQL-based setups as the primary warehouse, unless your needs are small or highly controlled” Perplexity Sonar Pro · Warehouse & ETL · negative prompt · soft negative

Names read as PostgreSQL

What the judge wrote, as written, with how often. The vendor table decides that these count as PostgreSQL; a claim can dispute any of them.

Claim this page

Claiming is free and changes nothing in the data. A claimed page gets a verified contact who is told when each edition publishes; the right to propose corrections to the vendor table, meaning names the judge wrote that should or should not read as PostgreSQL, applied by version and listed in the change log; and a logo and one-line description supplied by the vendor and marked as such.

It does not get any change to labels, shares or quadrants, any preview, or any say over which quotes appear. Sponsorship is separate: a sponsor funds categories or buyer dimensions and is named on what it funded, and the rules are the same for every sponsor.
