pg_dump w/ 8.0b2 and win2k

I am trying to dump a schema that was created on the windows version of
postgres. I am getting an error that I don't understand.. I can dump the
entire database with the superuser but dumping one schema doesn't seem
to work.

pg_dump -v -U proporg > temp1.sql

pg_dump: reading schemas
pg_dump: reading user-defined functions
pg_dump: reading user-defined types
pg_dump: reading procedural languages
pg_dump: reading user-defined aggregate functions
pg_dump: reading user-defined operators
pg_dump: reading user-defined operator classes
pg_dump: reading user-defined conversions
pg_dump: reading user-defined tables
pg_dump: SQL command failed
pg_dump: Error message from server: ERROR:  permission denied for

pg_dump: The command was: LOCK TABLE public.pg_ts_dict IN ACCESS SHARE MODE
pg_dump: *** aborted because of error
