I feel like I should know this, but I don't! š
When creating a new rails app with --database=postgresql the database.yml looks like:
...
default: &default
adapter: postgresql
encoding: unicode
# For details on connection pooling, see Rails configuration guide
# http://guides.rubyonrails.org/configuring.html#database-pooling
pool: <%= ENV.fetch("RAILS_MAX_THREADS") { 5 } %>
development:
<<: *default
database: big_bustas_development
...
Now I can do all manner of rails db:create ...migrate...ect without explitly configuring a database user and password. What postgres credentials is rails using the accomplish this?
