The connection string shown includes the username and password in it. Or are you referring to a different username/password here?

Thanks for the follow-up. I don't think it's safe to assume that the reader will know that this string contains the username and password (I didn't.). It's specially obscure in this case because it's just "postgres" repeated over and over throughout the string, instead of something like "admin" or "root" appearing to give the reader some clue.

Additionally, some (most?) DB-admin applications present a connection dialog that asks for a username and password. For example, I'm using Beekeeper Studio; its connection dialog takes a username and password as I've seen many others do.

Personally I think this is an advanced feature and anyone doing this would/should know about postgres connection strings and what they contain. In reference to your screenshot here, beekeeper studios and most if not all DB admin tools have an Import from URL feature like in your screenshot.

Agree with @silentworks here, I think this is OK to close as the information is there. If others experience this, please comment (or react with emojis) and we can look to include this.

Thanks for the replies, but I strongly disagree. I have used several major databases over the years, but never Postgres. I've programmed for MySQL (& MariaDB), SQL Server, SQLite, Oracle PL-SQL. It is completely reasonable to expect that someone's first exposure to Postgres will be motivated by his desire to use Supabase.

I don't understand the resistance to simply putting

(using the default username/password of postgres/postgres)

in the doc. It's 58 characters.
