Hi Pepe,
You are right. It got dropped after revoking the privileges.
Thank you so much,

Sound like this is actually an alias for DROP ROLE.

You have to explicitly drop any privileges associated with that user, also to move its ownership to other roles (or drop the object).
reassign owned by <olduser> to <nnewuser> ;
and then 
drop owned by <olduser>;
The latter will remove any privileges granted to the user.

I am trying to set up a new user for a client application, and thus want to remove the old user afterward.

The steps are:

1/ create the new user
2/ give the new user all priviliges on database, table, sequence, function and procedures, just like the old user
3/ deply client application with the new user and credentials
3/ Swap ownership of the databases
4/ Remove privileges from the old user
5/ Drop the old user

But I'm getting stuck on one last error message:

ERROR:  role "X" cannot be dropped because some objects depend on it
DETAIL:  privileges for default privileges on new functions belonging to role postgres in schema public

The "new functions" bit is confusing. I've swapped over all the current functions, but cannot seem to find the appropriate table for privileges on new functions.

What am I missing here?
