https://github.com/TechEmpower/FrameworkBenchmarks is a poupular nodejs benchmark:

This project provides representative performance measures across a wide field of web application frameworks.

I have noticied that most of the frameworks use postgres.js probabily because it claim to be the faster postgres client (I have also discussed here #3391 )

My suggestion is to mantains the nodejs benchmark https://github.com/TechEmpower/FrameworkBenchmarks/tree/master/frameworks/JavaScript/nodejs and take it updated with last version an improve it with:

• pg-native
• prepared statement

The goal is promote pg is better!
