Change ownership of a database

[Kevin Duffy <kevind0718@xxxxxxxxx>]

Hello all: 

I made a mistake.  Maybe I was lazy.

I created a database and did some amount of development as postgres.

Now I need to get this changed to a log-on role say xxx-db-owner.

I have a bunch of tables , functions and user defined types.

I have created the role: xxx-db-owner.

And most important I have db backups and have a copy of the db on the server under a different name.

And I have written the sql to to the changes for the tables, functions and user defined types.

Question:  the database and schema ownership needs to be changed also? 

         Is there an order I should do the changes in?

         Is there a way I can shoot myself in the foot here.

Many thanks for your attention to this matter.
