What a coincidence seeing this on HN. Great lib! I actually experimented with replacing our use of node-postgres with this today. Your lib was the reason I finally got around to shipping support for tagged template literals in Imba today (https://github.com/imba/imba/commit/ae8c329d1bb72eec6720108d...) :) Are you open for a PR exposing the option to return rows as arrays? It's pretty crucial for queries joining multiple tables with duplicate column names.
Brilliant! We're well on our way to migrating. The experience has been buttery smooth so far. And the codebase itself is really well organized. Huge thumbs up!
