Postgres : Change current user to root

Question

Complete database newbie here. I installed postgres on my laptop to run some local apps and stuff. However the fact that postgres is setup using myname instead of root is quite a hinderance. Any way I cant replace it with root ?

I open psql with this:

psql -h localhost

myname=# \l

              |        |          |             |             | myname=CTc/myname
 template1    | myname | UTF8     | en_US.UTF-8 | en_US.UTF-8 | =c/myname              +
              |        |          |             |             | myname=CTc/myname
(5 rows)

Thanks for the help

Simply set the two default databases ( template1 / template0 ) to the user you want, and all future / new databases would be created with this new user.

For eg

ALTER DATABASE template0 OWNER TO newname1;
ALTER DATABASE template1 OWNER TO newname1;
