Did the author write an actual parser, or does this mean they spent 10 hours coaxing Claude into writing this blog post?

There's not a lot of depth here, and this doesn't really feel like it says much.

The blog post mostly compares Postgres, MySQL, SQL Server... and then flips between comparisons to BigQuery occasionally, and Snowflake other times. Is that intentional (and is it accurate?), or did the LLM get confused?
