[GENERAL] "Database does not exist" weirdness

Hi folks,

Please excuse the question if I'm missing something stupid, but I seem to be stuck. I've created a postgres database,
viaan Elixir project setup, and it's showing up via psql's \l command, but I'm seeing "database does not exist"
messages.

Transcript of a session showing this follows below.

Anything I should be looking at, here? What am I missing?

Many thanks in advance,
Michael
