You can do

  drop owned by user_name;
  drop user user_name;

I know this commands thank yo =).
To use them you need to invoke this command in all database because roles sit atop of PG database  or you need to find
DBswhich has objects that depend on ROLE you want to delete. You can't do anything with objects in DB you are not
connected

The short answer is that DROP USER couldn't reach across databases to get
rid of owned objects in other databases.  See

Some security consideration bear in mind that DROP OWNED cant delete  own
objects in other DBs? In general what stops  us  to do inter DBs connection
like MSSQL?
