“an existing PostgreSQL or analytics platform may be sufficient if the workload is moderate and relational joins matter”Perplexity Sonar · Scale-constrained question · alternative

“Avoid using relational databases for high-scale time series workloads”Mistral Small · Negative question · warning
“Traditional relational databases (like MySQL or standard Postgres) often struggle with the high velocity, append-only nature”Qwen 3.7 Flash · Paraphrase question · warning
“Plain PostgreSQL or MySQL for very large time-series workloads... Use them cautiously”Perplexity Sonar · Negative question · warning

How this is measured
Fourteen AI models from 12 labs are asked the same buying questions six ways, for three company sizes. Standings refresh every edition.
Gane sells AI visibility software. No company can pay to change a result.
Read the method →Sources returned with these answers
Fourteen of the fourteen models returned a source list in this edition: five return the pages they cited and nine the search results they consulted. These counts come from 77 of the 99 answers that named PostgreSQL and are not a share of its labels.
Domains cited
156 of the 178 domain citations in answers naming PostgreSQL came from a third party's page. Twenty-two were to the publisher's own pages (the Gane Index), which the models cite like any other source; they are not counted as a third party.
Pages cited
Pages are listed as the models cited them.

How it is countedHide how it is counted
Every page postgresql.org exposes, subdomains included. Kind is read from the address and title. The last 90 days, the latest date and the twelve months count pages by when they were published, from the site's feeds, a date in the address, or the page's own publication date, read from up to a hundred of its most recently changed pages; a page that says only when it last changed is counted in its kind but not in when, so the recent counts are a floor, and a kind none of whose pages gives a publication date reads undated. An event counts as online when its address or title says so (webinar, on demand, virtual or online summit); a conference, summit, trade show, expo or roadshow that does not say so is counted as a conference or event, which on a vendor's site is mostly in person.
