Help wanted: one user for multiple database

hi
I am new in pgcat and I have not found a tutorial or the way to make a single user be able to manipulate all the databases
Is that possible?
Example in pgbouncer
 ```
[databases]
;; use auth_user with auth_query if user not present in auth_file
 * = auth_user=my_user_db
 or
* = host=172.19.0.157 user=my_my_userdb password=mypassword
 ```
