It's the first link in the readme: https://godoc.org/github.com/jackc/pgx

wow, well that's so small I looked for a day and did not find it. I suggest put a text link too, in addition to the button one in the status bar

One suggested improvement on the documentation, would be to provide a link to a page that discusses the various kinds of DB urls that can be used. Right now there seems to be a dearth of such documentation. It may well be that other projects document but they are not this project and if this project provides that useful information it will drive users toward the project. The only down side is that you may become too popular.
