I'm trying to decide whether to learn PostgreSQL or MongoDB for full stack web development. I've already started learning PostgreSQL, but I'm unsure if I should also pick up MongoDB or if learning just PostgreSQL will be enough for my needs.

There are way more projects relying on SQL databases than NoSQL. PostgreSQL is a solid choice for learning, especially if you check out the job market in your area – many companies prefer PostgreSQL over others like MongoDB.
PostgreSQL is definitely the way to go. It's solid and versatile – you'll cover most full-stack scenarios with it. Save MongoDB for if you come across a project needing that schema flexibility or handling lots of unstructured data.
To make it clear, just stick with PostgreSQL. It's more than sufficient for your needs in full stack development. MongoDB can come later when you face specific projects that demand it.
