database dump then restore on another system?

To date I have always used pg on a system where I had pg superuser status.
I'm trying to move a database from such a system to one where I am just
a user, and I'm having a couple of problems.

The first is, the output of pg_dump has a lot of lines like:

ALTER FUNCTION some_function OWNER TO rick;

The user 'rick' does not exist on the target system.  I've looked at the
help for pg_dump...it looks like specifying "no-owner" will skip these
lines.  Are there any side effects I need to be aware of?

The second problem is the statement:

CREATE PROCEDURAL LANGUAGE plpgsql;

Apparently I need to be a pg superuser to do this?  Do I need to get the
db admin to run this statement before I load the database?  What if,
during testing, I need to drop/create the database?  Do I need the admin
to run something every time?
