Hi erik,
There is no such default password for user Postgres. The password needs to be set.
Please find below details:
1. Login to the machine where PostgreSQL is installed. Use below command from terminal to connect to the cluster.
psql -U postgres
- If the PATH is not set, above command will give an error. Below is the default PATH for PostgreSQL binaries.
/Applications/Postgres.app/Contents/Versions/latest/bin/
2. After successful login use below command to set the password:
ALTER ROLE postgres PASSWORD 'postgres';
Hope this helps.
