I think one interesting angle would be to integrate your assertions directly into Postgres as a plugin. That way, you can spy on every query issued in any test framework, dump the text automatically, and prove additional assertions about the query plan index use perf etc, regardless of the user’s primary language. That would also get you out of needing to build 1000 different integrations for all the programming language / ORM combos in the universe. If you don’t want to do a Postgres plugin you could also do this as a Postgres wire protocol proxy.
