Is your driver DB setting in config/db.php set to mysql? (It should be pgsql if you’re using Postgres.)

If it’s set to App::env('DB_DRIVER') (as it is by default), check the DB_DRIVER environment variable in your .env file.

Hi @brandonkelly it was set too mysql as the install seemed to copy the .example.env file, I then followed the instructions and tried to load the screen and the error message was displayed. I tried changing this to pgsql as you mentioned but I was still presented with the same error.

I feel like there is a missing step?

Are you able to run php craft setup/db-creds and have that complete successfully?

I haven't tried that to be honest I'll come back to you.
