I could be wrong. That's one thing I'm trying to figure out. Setting that aside, like I said I don't really know that community, being mostly a Java developer. What're the go to database libraries? Is it sequelize, or something else?

Slonik is much newer, and is Postgres only. But there is a general trend seen in many different projects that support safe SQL execution using tagged template literals in JavaScript, which is a fantastic technology. Slonik was one of the first projects that went this route, but there are now many others.
In general I think it's a mistake to look for a single "market leader" for node DB access. There are many high quality libraries that are favored by different teams for various reasons.
