Q: How do I disable password checking for createlang?

I think this should be a simple thing: 
   When I run create createlang, it asks for a password.
   I don't want it to because `psql mydb` does not require a password.
   



I CAN GET INTO mydatabase WITHOUT A PASSWORD:
  [russianspy@server1 slony]$ sudo su postgres
  bash-3.00$ psql mydatabase
  Welcome to psql 7.4.8, the PostgreSQL interactive terminal.
  
  Type:  \copyright for distribution terms
         \h for help with SQL commands
         \? for help on internal slash commands
         \g or terminate with semicolon to execute query
         \q to quit
  
  mydatabase=# \q


BUT I CAN'T RUN createlang WITHOUT A PASSWORD:
  [russianspy@server1 slony]$ sudo su postgres
  bash-3.00$ createlang -h localhost -p 5432 plpgsql mydatabase
  Password:
 

** I wan't to disable this password prompt on createlang - what do I do ? **

ANSWER: 
1) change all entries to 'trust' in the pg conf file
2) restart postgresql server.
