This does look like it's a little bit better than a lot of the other options in the Go ecosystem for database access, but this introduction misses something important: what SQL dialects does this support? It appears to be partly a wrapper around Squirrel. Squirrel is not new (and apparently also no longer being updated) but I actually have no idea which and how much of each SQL dialect Squirrel supports.
Every time I see SQL and Go stuff, I feel literally obligated to introduce people to sqlc. That said, sqlc only has good support for PostgreSQL, and you'd have to generate code for each dialect... so that's something worth considering. (I still find it to be one of my favorite SQL tools, even with its issues.)
