+ Normally, the creator becomes the owner of the new database.
+ A different owner may be specified by using the

+ To create a database owned by oneself, either superuser privilege
+ or CREATEDB privilege is required. A superuser may create a database
+ for another user, even if that user has no special privileges himself.
There is no CREATE DATABASE statement in SQL92.

Access privileges on functions
Access privileges on procedural languages
+CREATE DATABASE has OWNER option so superuser can create DB for someone else
