pg_dumpall outputs incorrect sql

I have a database in which there is a user and their search path is set to:

dbmirror, public, pg_catalog

pg_dumpall includes this line in the dump:

ALTER USER dbmirror SET search_path TO 'dbmirror, public, pg_catalog';

This isn't correct though, because when it is run through psql to load
the user, I get the following:

psql:globals.dump:17: ERROR: schema "dbmirror, public, pg_catalog" does
not exist

However, if I take the quotes off the search_path it works perfectly. Is
there something I'm not doing right or is this a bug?

I'm using Postgres 7.4.3
